Merge main into fix/db-off-data-plane-469

Brings in the two commits main gained: #472 (CLI cleanup — remove `info`,
split `list active` into a top-level `active`, simplify `list`) and the
terminology glossary. #472 was written against the old flat cli/ layout,
so its semantics are reconciled into the reorg'd cli/commands/ structure:

  * new `active` command lives at cli/commands/active.py, registered in
    the lazy registry and listed in `help` (not left at the flat path).
  * `info` removed: deleted cli/commands/info.py, dropped from the
    registry and `help`.
  * `list` simplified to list-available-only, using the reorg's
    os.getcwd()/constants.PROG conventions.
  * the `list active` -> `active` doc wording applied to the backend
    docstrings that our split moved into base.py / selection.py.

Our reorg wins for the fully-rewritten dispatcher (cli/__init__ shim,
backend facade). pyright: 0 errors. Full unit suite green (2243).

+# Glossary
+
+Canonical terminology for bot-bottle. Prefer these names in docs, comments, and UI.
+
+---
+
+## Agent Provider
+
+The component that connects to an external model provider and sets up the model
+harness inside the agent runtime. Configured in a bottle manifest under
+`agent_provider:`; built-in templates are `claude` and `codex`. Responsible for
+provider-specific auth, startup args, and egress routes.
+
+## Agent Runtime
+
+The OCI image (and the container or VM it runs in) that houses the model
+harness. On the macOS-container backend this is an Apple Container; on
+Firecracker it is a microVM; on the legacy Docker backend it is a Docker
+container. The agent runtime is built from the agent provider's Dockerfile
+(built-in or custom).
+
+## Agent / Agent Definition
+
+A Markdown file with YAML frontmatter that declares the system prompt and
+identity of the model harness. Lives under `~/.bot-bottle/agents/` or a repo's
+`.bot-bottle/agents/`. Specifies which bottle to run under (`bottle:`) and
+which skills to load. Agent definitions are safe to commit; they contain no
+secrets or egress policy.
+
+## Bottle / Bottle Definition
+
+A Markdown file with YAML frontmatter that declares the security and runtime
+boundaries for one agent runtime: egress allowlist, git remotes, env vars,
+nested-container flag, and agent provider config. Lives under
+`~/.bot-bottle/bottles/`. Bottles are scoped to `$HOME` so a cloned repo
+cannot override host egress policy.
+
+## Sealed Bottle
+
+The fully-resolved bottle after all `extends:` inheritance is applied and every
+field has been validated. The sealed bottle is the immutable boundary spec that
+the launcher enforces — no further overrides are possible once it is sealed.
+
+## Bottled Agent
+
+The combination of an Agent Definition and a Sealed Bottle, representing a
+single deployable agent with a fixed identity and fixed boundaries. A bottled
+agent has two observable states:
+
+- **Active** — the agent runtime is running and the agent is executing.
+- **Frozen** — the agent runtime has been snapshotted (Firecracker committed
+  image); the agent is not running but can be resumed from the snapshot.
+
+## Active Bottle
+
+Shorthand for an active (running) Bottled Agent. Used in the supervisor TUI
+and discovery layer to mean "a bottle whose agent runtime is currently up."
