refactor: drop redundant single-parent fast path in _resolve_one_bottle

_fold_parents with one name returns after the first resolve; the
single-element branch was a verbatim copy of the general path.

+"""capability_apply — host-side orchestrator for capability-block

+
+On approval of a capability-block proposal, the dashboard calls
+apply_capability_change(slug, new_dockerfile) which:
+
+  1. Snapshots the agent's transcript dir to
+     ~/.bot-bottle/state/<slug>/transcript/ (best-effort).
+  2. Pushes the agent's working tree via `git push` (best-effort —
+     no upstream / no commits / no git repo all skip with a log).
+  3. Writes the new Dockerfile to
+     ~/.bot-bottle/state/<slug>/Dockerfile (PRD 0016 Phase 1
+     state). The next `cli.py start <agent>` picks it up.
+  4. Force-removes the agent container + all sidecars + the
+     per-bottle networks. Idempotent — missing resources are not
+     errors.
+
+Returns (before, after) Dockerfile contents so the dashboard can
+record / render the diff. (capability-block has no audit log per
+PRD 0013 — the per-bottle Dockerfile state is its own record.)
+
+This is "fire-and-forget" from the agent's perspective: by the time
+the dashboard writes the response file the supervise sidecar is
+gone, so the agent's tool call connection drops without ever
+receiving the response. The replacement agent (next manual
+`cli.py start`) sees the new Dockerfile and starts from there.

-# PRD 0066: Separate agent and bottle selection
-
-- **Status:** Active
-- **Author:** claude
-- **Created:** 2026-06-25
-- **Issue:** #269
-
-## Summary
-
-Agents and bottles are two separate concerns: agents carry a system prompt and
-skills; bottles carry infrastructure configuration (egress, git-gate, env,
-agent provider). Today an agent's manifest file hard-codes a single `bottle:`
-reference, which prevents the same agent prompt from being reused across
-projects that need different bottle configurations. This PRD decouples them: at
-launch time, after choosing the agent, the operator picks an ordered list of
-bottles via a multi-select picker. The selected bottles are merged in order
-(later entries override earlier ones) to produce the effective bottle for the
-session.
-
-## Problem
-
-The current `bottle: <name>` field on an agent manifest file binds the agent
-permanently to one bottle. To use the same system prompt with a different bottle
-(e.g. `claude-implementer` at home vs. at a client site that needs a different
-egress policy), the operator must duplicate the agent file and change the
-`bottle:` field. Duplicate agent files drift out of sync.
-
-## Goals / Success Criteria
-
-1. `bottle:` in an agent's frontmatter becomes optional. Existing manifests with
-   `bottle:` continue to work unchanged (backward compat).
-2. After selecting an agent (via the existing single-select picker), a new
-   multi-select bottle picker appears showing all available bottles.
-3. The multi-select picker pre-populates with the agent's `bottle:` value when
-   present.
-4. Confirming with one or more bottles selected uses those bottles, merged in
-   selection order, as the effective bottle for the session.
-5. Confirming with an empty selection falls back to the agent's `bottle:` field.
-   If neither is set, a ManifestError is raised pointing the operator at the fix.
-6. The ordered bottle list is stored in launch metadata so `./cli.py resume`
-   uses the same bottles.
-7. The preflight summary (`y/N` screen) shows the effective bottle name(s).
-8. The multi-select picker supports incremental filtering, Space/Enter to toggle
-   selection, an ordered "Selected: ..." summary line, Ctrl-D to confirm, and
-   Esc/q to cancel the whole start operation.
-9. Unit tests cover: multi-select widget (filter, toggle, confirm, cancel),
-   the `cmd_start` bottle-picker step, and the manifest `load_for_agent`
-   runtime-bottle-merge path.
-
-## Non-goals
-
-- Reordering the selection list from within the picker (order = insertion order;
-  drag-and-drop is out of scope).
-- Storing bottle selection history / MRU.
-- Changes to `./cli.py edit`, `./cli.py list`, or `./cli.py info`.
-- Removing the `bottle:` key from the agent schema (it stays, now optional).
-
-## Design
-
-### `bot_bottle/cli/tui.py` — `filter_multiselect`
-
-```python
-def filter_multiselect(
-    items: list[str],
-    *,
-    title: str = "",
-    initial: list[str] | None = None,
-    tty_path: str = "/dev/tty",
-) -> list[str] | None:
-    """Multi-select variant of filter_select.
-
-    Returns the ordered list of selected items, or None on cancel.
-    Press Space/Enter to toggle the item under the cursor.
-    Press Ctrl-D to confirm. Press Esc/q to cancel.
-    """
-```
-
-Layout:
-
-```
-Select bottles
-Filter: _
-─────────────────────────────────────────
-> [*] claude
-  [ ] dev
-  [ ] codex
-─────────────────────────────────────────
-Selected (in order): claude
-─────────────────────────────────────────
-[↑↓/jk] move  [Space] toggle  [Ctrl-D] done  [Esc] cancel
-```
-
-`initial` pre-populates the ordered selection. `None` means no pre-selection.
-Items added are appended in insertion order; items removed leave the remaining
-order unchanged.
-
-### `bot_bottle/manifest_schema.py` — optional `bottle:`
-
-`bottle` moves from `AGENT_KEYS_REQUIRED` to `AGENT_KEYS_OPTIONAL`.
-
-### `bot_bottle/manifest_agent.py` — optional `bottle:`
-
-`ManifestAgent.bottle` changes from `str` (required) to `str = ""`.
-`from_dict` no longer requires the key to be present; the bottle-exists
-validation is skipped when the key is absent.
-
-### `bot_bottle/manifest_loader.py` — `scan_bottle_names`
-
-```python
-def scan_bottle_names(bottles_dir: Path) -> list[str]:
-    """Scan <bottles_dir>/*.md and return sorted bottle names."""
-```
-
-### `bot_bottle/manifest.py` — `ManifestIndex` changes
-
-**`all_bottle_names` property** — analogous to `all_agent_names`; scans
-`home_md / "bottles"` in lazy mode, returns `sorted(self.bottles.keys())` in
-eager mode.
-
-**`load_for_agent(agent_name, bottle_names: tuple[str, ...] = ())`** — new
-`bottle_names` parameter. When non-empty, the listed bottles are resolved and
-merged in order (index 0 is the base; each subsequent bottle is applied on top
-using the same field-merge rules as `extends:`). The result replaces the bottle
-that `agent.bottle` would have provided. When empty, falls back to `agent.bottle`.
-Raises ManifestError if neither `bottle_names` nor `agent.bottle` is set.
-
-### `bot_bottle/manifest_extends.py` — `merge_bottles_runtime`
-
-```python
-def merge_bottles_runtime(bottles: list[ManifestBottle]) -> ManifestBottle:
-    """Merge an ordered list of pre-resolved ManifestBottle objects.
-
-    Index 0 is the base; each subsequent entry overrides the previous using
-    the same rules as the file-based extends machinery:
-      - env: dict merge, later wins
-      - git_user: per-field overlay, later wins on non-empty
-      - git (repos): union by name, later wins per-name
-      - egress.routes: concatenate
-      - agent_provider, supervise: later bottle's value replaces earlier
-    """
-```
-
-This function operates on already-parsed `ManifestBottle` objects, so it does
-not need to touch the raw-dict path.
-
-### `bot_bottle/backend/__init__.py` — `BottleSpec` + `_validate`
-
-`BottleSpec` gains `bottle_names: tuple[str, ...] = ()`.
-
-`BottleBackend._validate` passes `spec.bottle_names` to `load_for_agent`:
-
-```python
-manifest = spec.manifest.load_for_agent(spec.agent_name, spec.bottle_names)
-```
-
-The preflight print updates `info(f"bottle: {agent.bottle}")` to display the
-effective bottle name(s). When `spec.bottle_names` is non-empty those are
-shown; when empty and `agent.bottle` is set, the agent's `bottle:` is shown.
-
-### `bot_bottle/bottle_state.py` — persist bottle names
-
-`BottleMetadata` gains `bottle_names: tuple[str, ...] = ()`. `read_metadata`
-reads this from JSON (default `()`). `write_launch_metadata` passes
-`spec.bottle_names` through.
-
-### `bot_bottle/cli/start.py` — bottle multiselect step
-
-After agent selection, before the name/color modal:
-
-```python
-available_bottle_names = manifest.all_bottle_names
-# Peek at agent's bottle default for pre-population
-initial_bottle = _peek_agent_bottle(manifest, agent_name)
-initial = [initial_bottle] if initial_bottle else []
-
-bottle_names_list = tui.filter_multiselect(
-    available_bottle_names,
-    title="Select bottles",
-    initial=initial,
-)
-if bottle_names_list is None:
-    return 0  # user cancelled
-bottle_names = tuple(bottle_names_list)
-```
-
-`_peek_agent_bottle` reads the agent file's frontmatter without full parsing,
-returning the `bottle:` value or `""` when absent.
-
-`BottleSpec` is built with `bottle_names=bottle_names`.
-
-### `bot_bottle/cli/resume.py` — bottle names from metadata
-
-```python
-spec = BottleSpec(
-    ...
-    bottle_names=tuple(metadata.bottle_names),
-)
-```
-
-## Implementation chunks
-
-1. **Schema + model** — `manifest_schema.py`, `manifest_agent.py` (optional
-   `bottle:`), `manifest_loader.py` (`scan_bottle_names`), `manifest.py`
-   (`all_bottle_names`, `load_for_agent` signature), `manifest_extends.py`
-   (`merge_bottles_runtime`), `bottle_state.py` (`bottle_names` field),
-   `resolve_common.py` (thread through).
-2. **Backend** — `BottleSpec.bottle_names`, `_validate`, preflight print.
-3. **TUI** — `filter_multiselect` in `tui.py` + unit tests.
-4. **CLI wiring** — `start.py` bottle picker step, `resume.py` metadata load.
-5. **Tests** — `test_cli_start_selector.py` bottle-picker cases,
-   `test_manifest_agent.py` optional-bottle cases, new
-   `test_manifest_bottle_merge.py` for `merge_bottles_runtime`.
