* feat: streaming container mode, IPC messaging, agent teams support
Major architectural shift from single-shot container runs to long-lived
streaming containers with IPC-based message injection.
- Agent runner: query loop with AsyncIterable prompt to keep stdin open
for agent teams (fixes isSingleUserTurn premature shutdown)
- New standalone stdio MCP server (ipc-mcp-stdio.ts) inheritable by
subagents, with send_message and schedule_task tools
- Streaming output: parse OUTPUT_START/END markers in real-time, send
results to WhatsApp as they arrive
- IPC file-based messaging: host writes to ipc/{group}/input/, agent
polls for follow-up messages without respawning containers
- Per-group settings.json with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
- SDK bumped to 0.2.34 for TeamCreate tool support
- Container idle timeout (30min) with _close sentinel for shutdown
- Orphaned container cleanup on startup
- alwaysRespond flag for groups that skip trigger pattern check
- Uncaught exception/rejection handlers with timestamps in logger
- Combined SDK documentation into single deep dive reference

* chore: remove unused ipc-mcp.ts (replaced by ipc-mcp-stdio.ts)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: clarify agent communication model in docs and tool descriptions
- CLAUDE.md (main + global): split communication instructions into
"responding to messages" vs "scheduled tasks" sections
- send_message tool: note that scheduled task output is not sent to user
- Remove structured output (outputFormat) — not needed with current flow
- Regular output is sent to WhatsApp; scheduled task output is only logged

* chore: ignore dynamic group data while preserving base structure
Only track groups/main/CLAUDE.md and groups/global/CLAUDE.md. All other
group directories and files are ignored to prevent tracking user-specific
session data.

* fix: resolve critical bugs in streaming container mode
Bug 1 (scheduled task hang): Task scheduler now passes onOutput callback
with idle timer that writes _close sentinel after IDLE_TIMEOUT, so
containers exit cleanly instead of blocking queue slots for 30 minutes.
Scheduled tasks stay alive for interactive follow-up via IPC.
Bug 2 (timeout disabled): Remove resetTimeout() from stderr handler.
SDK writes debug logs continuously, resetting the timer on every line.
Timeout now only resets on actual output markers in stdout.
Bug 3 (trigger bypass): Piped messages in startMessageLoop now check
trigger pattern for non-main groups. Non-trigger messages accumulate in
DB and are pulled as context via getMessagesSince when a trigger arrives.
Bug 7 (non-atomic IPC writes): GroupQueue.sendMessage uses temp file +
rename for atomic writes, matching ipc-mcp-stdio.ts pattern.
Also: flip isVerbose back to false (debug leftover), add isScheduledTask
to host-side ContainerInput interface.

* fix: idle timer not starting + scheduled task groupFolder missing
Two bugs that prevented the scheduled task idle timeout fix from working:
1. onOutput was only called when parsed.result !== null, but session
update markers have result: null. The idle timer never started for
"silent" query completions, leaving containers parked at
waitForIpcMessage until hard timeout.
2. Scheduler's onProcess callback didn't pass groupFolder to
queue.registerProcess, so closeStdin no-oped (groupFolder was null).
The _close sentinel was never written even when the idle timer fired.

* fix: duplicate messages and timestamp rollback in piping path
Two bugs introduced by the trigger context accumulation change:
1. processGroupMessages didn't advance lastAgentTimestamp until after
the container finished. The piping path's getMessagesSince(lastAgent
Timestamp) re-fetched messages already sent as the initial prompt,
causing duplicates.
2. processGroupMessages overwrote lastAgentTimestamp with the original
batch timestamp on completion, rolling back any advancement made by
the piping path while the container was running.
Fix: advance lastAgentTimestamp immediately after building the prompt,
before starting the container. This matches the piping path behavior
and eliminates both the overlap and the rollback.

* fix: container idles 30 extra minutes after _close during query
When _close was detected during pollIpcDuringQuery, it was consumed
(deleted) and stream.end() was called. But after runQuery returned,
main() still emitted a session-update marker (resetting the host's idle
timer) and called waitForIpcMessage (which polled forever since _close
was already gone). The container had to wait for a second _close.
Fix: runQuery now returns closedDuringQuery. When true, main() skips
the session-update marker and waitForIpcMessage, exiting immediately.

* fix: resume branching, internal tags, and output forwarding
- Fix resume branching: pass resumeSessionAt with last assistant UUID
to anchor each query loop resume to the correct conversation tree
position. Prevents agent responses landing on invisible branches
when agent teams subagents create parallel JSONL entries.
- Add <internal> tag stripping: agent can wrap internal reasoning in
<internal> tags which are logged but not sent to WhatsApp. Prevents
duplicate messages and internal monologue reaching users.
- Forward scheduled task output: scheduled tasks now send result text
to WhatsApp (with <internal> stripping), matching regular message
behavior. No more special-case instructions.
- Update Communication guidance in CLAUDE.md: simplified to "your
output is sent to the user or group" with soft guidance on
<internal> tags and send_message usage.
- Add messaging behavior docs to schedule_task tool: prompts the
scheduling agent to include guidance on whether the task should
always/conditionally/never message the user.
- Mount security: containerPath now optional, defaults to basename
of hostPath.

* fix: cursor rollback on error, flush guard, verbose logging
- Roll back lastAgentTimestamp on container error so retries can
re-process the messages instead of silently losing them.
- Add guard flag to flushOutgoingQueue to prevent duplicate sends
from concurrent flushes during rapid WA reconnects.
- Revert isVerbose from hardcoded false back to env-based check
(LOG_LEVEL=debug|trace).

* fix: orphan container cleanup was silently failing
The startup cleanup used `container ls --format {{.Names}}` which is
Docker Go-template syntax. Apple Container only supports `--format json`
or `--format table`. The command errored with exit code 64, but the
catch block silently swallowed it — orphan containers were never cleaned
up on restart.
Fixed to use `--format json` and parse `configuration.id` from the
JSON output. Also filters by `status: running` and logs a warning on
failure instead of silently catching.

* docs: add Discord badge and community section

* fix: idle timer reset on null results and flush queue message loss
- Only reset idle timer on actual results (non-null), not session-update
markers. Prevents containers staying alive 30 extra minutes after the
agent finishes work.
- flushOutgoingQueue now uses shift() instead of splice(0) so unattempted
messages stay in the queue if an unexpected error bails the loop.

* fix: wire up queue processMessagesFn before recovery to prevent silent message loss
recoverPendingMessages() was called after startMessageLoop(), which meant:
1. Recovery could race with the message loop's first iteration
2. processMessagesFn was set inside startMessageLoop, so recovery
enqueues would fire runForGroup with processMessagesFn still null,
silently skipping message processing
Move setProcessMessagesFn and recoverPendingMessages before startMessageLoop
so the queue is fully wired before any messages are enqueued.

* feat: structured agent output to fix infinite retry on silent responses (#113)
Use Agent SDK's outputFormat with json_schema to get typed responses
from the agent. The agent now returns { status: 'responded' | 'silent',
userMessage?, internalLog? } instead of a plain string. This fixes a
critical bug where a null/empty agent response caused infinite 5-second
retry loops by conflating "nothing to say" with "error".
- Agent runner: add AGENT_RESPONSE_SCHEMA and parse structured_output
- Host: advance lastAgentTimestamp on both responded AND silent status
- GroupQueue: add exponential backoff (5s-80s) with max 5 retries for
actual errors, replacing unbounded fixed-interval retries

Scheduled tasks can now run in either:
- "group" mode: uses the group's conversation session for context
- "isolated" mode: runs with a fresh session (previous behavior)
The tool description guides the agent on when to use each mode and
prompts them to ask the user if unclear. Group mode is now the default.
