  The Claude Code ACP adapter announces its slash commands with a
  `session/update` of kind `available_commands_update`; the bridge already relayed it
  verbatim but the SPA ignored it.

  Implemented (2026-09-17):
  - Reducer: `available_commands_update` stores `commands` in `ChatState` (typed
    `AcpAvailableCommand` in `ui/src/protocol.ts`), cleared on `hello`.
  - Composer: the commands are merged into the `/` popup with the skills discovered on
    disk (ticket 0012), deduplicated by name and tagged "command"; picking one inserts
    `/<name> ` — the text in `session/prompt` is the invocation mechanism.
  - Mock agent: emits one `available_commands_update` (`review`, `compact`) at session
    start so `make run-mock` exercises the feature; covered by a Go test.
