- cancel_by_session: use asyncio.gather for parallel cancellation
instead of sequential await per task
- _dispatch: register in _active_tasks before acquiring lock so /stop
can find queued tasks (synced from #1179)
- SubagentManager tracks _session_tasks: session_key -> {task_id, ...}
- cancel_by_session() cancels all subagents for a session
- SpawnTool passes session_key through to SubagentManager
- /stop response reports subagent cancellation count
- Cleanup callback removes from both _running_tasks and _session_tasks
Builds on #1179
- Add commands.py with CommandDef registry, parse_command(), get_help_text()
- Refactor run() to dispatch messages as asyncio tasks (non-blocking)
- /stop is an 'immediate' command: handled inline, cancels active task
- Global processing lock serializes message handling (safe for shared state)
- _pending_tasks set prevents GC of dispatched tasks before lock acquisition
- _dispatch() registers/clears active tasks, catches CancelledError gracefully
- /help now auto-generated from COMMANDS registry
Closes#849
The slackify_markdown library (markdown-it) fails to convert **bold** when
the closing ** is immediately followed by non-space text (e.g. **Status:**OK).
This is a very common LLM output pattern that results in raw ** showing up
in Slack messages.
Add _fixup_mrkdwn() post-processor that:
- Converts leftover **bold** → *bold* (Slack mrkdwn)
- Converts leftover ## headers → *bold* (safety net)
- Fixes over-escaped & in bare URLs
- Protects code fences and inline code from being mangled

The slackify_markdown library misses several patterns that LLMs commonly
produce, causing raw Markdown symbols (**bold**, ##headers) to appear
in Slack messages.
Add _fixup_mrkdwn() post-processor that:
- Converts leftover **bold** patterns (e.g. **Status:**OK where closing
** is adjacent to non-space chars)
- Fixes & over-escaping in bare URLs
- Protects code blocks from false-positive fixups

- Defer Brave API key resolution to execute() time instead of __init__,
so env var or config changes take effect without gateway restart
- Improve error message to reference actual config path
(tools.web.search.apiKey) instead of only mentioning env var
Fixes#1069 (issues 1 and 2 of 3)
