test: fix cli selector typing

Three UX improvements requested in #270 review:

- filter_multiselect: Space toggles selection, Enter confirms (was both)
- bottle picker: bottles with extends chains show ancestry labels
  (e.g. 'claude-dev <- bot-bottle-dev <- dev') for at-a-glance lineage
- preflight: replaces key-value summary with YAML of the resolved manifest

+"""capability_apply — host-side orchestrator for capability-block
+remediation (PRD 0016).
+
+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.
+v1 does not auto-relaunch — see PRD 0016's capability-block return
+semantics open question.

-
-## Summary
-
-Allow a bottle's `extends:` field to accept either a single bottle name (existing
-behavior) or a list of bottle names (new). Multiple parents are resolved
-independently and folded left-to-right into a single effective parent before the
-child is merged on top. This lets orthogonal concerns (base env, networking/egress,
-agent provider) live in separate bottles and be composed without forcing them into a
-linear chain.
-
-## Problem
-
-PRD 0025 shipped single-parent `extends:` and listed "No multi-parent inheritance"
-as a non-goal. In practice, users want to compose multiple orthogonal bottles — a
-base environment, a networking profile, and an agent-provider override — without
-creating a three-level linear chain that couples unrelated parents to each other.
-The linear chain workaround has two problems:
-
-1. **Ordering constraint.** `networking extends base` works, but then
-   `agent extends networking` can't also pick up `base` without going through
-   `networking`, coupling two unrelated concerns.
-
-2. **Quadratic duplication.** N orthogonal bottles require O(N²) chain variants
-   (one chain per permutation of applied concerns).
-
-Multi-parent `extends:` removes both constraints: each orthogonal concern stays in
-its own bottle, and the child bottle is the only place that names the combination.
-
-## Goals / Success Criteria
-
-- `extends:` accepts a list of strings in addition to a plain string.
-- Backward compat: existing single-string `extends:` is unchanged.
-- Parents are resolved left-to-right; later entries win on conflict.
-- Child wins over all parents (unchanged from PRD 0025).
-- Cycle detection covers multi-parent graphs, not just linear chains.
-- Diamond inheritance: a shared ancestor is resolved once (via the existing cache).
-- Invalid list entries (non-string, undefined bottle, self-reference) die at parse
-  with clear messages.
-- `manifest_loader.py`'s `load_bottle_chain_from_dir` enqueues all parents from a
-  list `extends:` so the resolver sees every bottle in the graph.
-
-## Non-goals
-
-- No change to the agent-vs-bottle trust boundary (PRD 0025 "Alternatives
-  considered" option 2 stays rejected).
-- No MRO / C3 linearization. Left-to-right fold is sufficient for the expected use
-  cases.
-- No preflight display of per-field provenance across multiple parents (same open
-  question as PRD 0025; remains a follow-up).
-
-## Design
-
-### Schema
-
-`extends:` now accepts either form:
-
-```yaml
-# single parent (unchanged)
-extends: base
-
-# multiple parents (new)
-extends: [base, networking]
-```
-
-Both forms are normalized to a list internally. A list with one element behaves
-identically to the string form.
-
-### Merge rules for multi-parent fold
-
-Parents are folded pairwise left-to-right before the child merge. For each step in
-the fold, the "earlier" bottle is the running accumulator and the "later" bottle is
-the next parent. Rules per field:
-
-| Field              | Fold rule                                                    |
-|--------------------|--------------------------------------------------------------|
-| `env`              | dict merge; later wins on key collision                      |
-| `git-gate.user`    | per-field overlay; later's non-empty fields win              |
-| `git-gate.repos`   | union by name; for same-name entries, later wins per-field   |
-| `egress.routes`    | concatenate (earlier first, later appended)                  |
-| `egress.log`       | later wins (last-wins)                                       |
-| `agent_provider`   | later wins (last-wins)                                       |
-| `supervise`        | later wins (last-wins)                                       |
-
-After the fold, the combined parent is merged against the child using the existing
-PRD 0025 rules (child always wins). The child's `egress.routes` appends to the
-combined parent's concatenated routes; `validate_egress_routes` runs once on the
-final merged set and catches duplicate hosts.
-
-### Algorithm
-
-```
-extends: [p1, p2, p3]
-
-fold:
-  combined = resolve(p1)
-  combined = fold_two(combined, resolve(p2))
-  combined = fold_two(combined, resolve(p3))
-
-merge:
-  result = _merge_bottles(combined, child_raw, name)
-```
-
-`fold_two(earlier, later)` applies the rules in the table above. Cycle detection
-(the `seen` tuple) is passed to each parent resolution call unchanged — if any
-parent's chain circles back to the current bottle, it is caught. The `cache` dict
-ensures a shared ancestor is only resolved once across all parents.
-
-### Error cases
-
-| Condition                              | Error message shape                                              |
-|----------------------------------------|------------------------------------------------------------------|
-| `extends` is not a string or list      | `extends must be a string or list of strings (was <type>)`       |
-| A list entry is not a string           | `extends[<i>] must be a string (was <type>)`                     |
-| A list entry names an undefined bottle | `extends '<name>' which is not defined. Available bottles: ...`  |
-| A list entry is the bottle itself      | `extends itself; remove the self-reference`                      |
-| Cycle through any parent edge          | `is in an extends cycle: <chain>`                                |
-
-## Implementation
-
-### `bot_bottle/manifest_extends.py`
-
-- `_resolve_one_bottle`: accept `str | list[str]` for `extends`; normalize to list;
-  validate each entry; for a single-entry list fall through to the existing
-  single-parent path; for multiple entries call `_fold_parents` then
-  `_merge_bottles`.
-- `_fold_parents(parent_names, raws, cache, repos_cache, seen)`: resolve each
-  parent and fold pairwise left-to-right; return `(effective_bottle,
-  effective_repos_raw)`.
-- `_fold_two_bottles(earlier, earlier_repos_raw, later, later_repos_raw)`: apply
-  the fold rules above; return `(folded_bottle, folded_repos_raw)`.
-
-### `bot_bottle/manifest_loader.py`
-
-- `load_bottle_chain_from_dir`: when `extends` is a list, enqueue all parent names
-  for loading (previously only `isinstance(parent, str)` was handled).
-
-### `tests/unit/test_manifest_extends.py`
-
-- `TestExtendsErrors.test_non_string_extends_dies`: update to use an integer
-  `extends` value (a list is now valid).
-- New class `TestExtendsMultiParent` covering all cases listed in the issue.
-
-## Testing strategy
-
-Unit tests via `ManifestIndex.from_json_obj` (same resolver surface used by all
-paths). No integration test changes needed — downstream code consumes the already-
-merged bottle and is unchanged.
-
-Test cases:
-- Two-parent list: env union, egress routes concat, git repos union
-- Last-parent-wins on scalar (supervise, agent_provider)
-- Child wins over all parents on conflict
-- Diamond: two parents share an ancestor; ancestor resolved once
-- Single-element list: identical to string form
-- Non-string extends value → ManifestError
-- Non-string list entry → ManifestError
-- Undefined bottle in list → ManifestError
-- Self-reference in list → ManifestError
-- Cycle through multi-parent edge → ManifestError
