Replace the stub `handle_bug_report` handler with a real implementation
that logs a decision trail and dispatches code_fix tasks to Forge for
automated fixing. Add `POST /api/bugs/submit` endpoint and `timmy
ingest-report` CLI command so AI test runners (Comet) can submit
structured bug reports without manual copy-paste.
- POST /api/bugs/submit: accepts JSON reports, creates bug_report tasks
- timmy ingest-report: CLI for file/stdin JSON ingestion with --dry-run
- handle_bug_report: logs decision trail to event_log, dispatches
code_fix task to Forge with parent_task_id linking back to the bug
- 18 TDD tests covering endpoint, handler, and CLI

The chat WebSocket return path was broken by two bugs that prevented
Timmy's responses from appearing in the live chat feed:
1. Frontend checked msg.type instead of msg.event for 'timmy_response'
events — the WSEvent dataclass uses 'event' as the field name.
2. Frontend accessed msg.response instead of msg.data.response — the
response payload is nested in the data field.
Additional fixes:
- Queue acknowledgment ("Message queued...") no longer logged as an
agent message in chat history; the real response is logged by the
task processor when it completes, eliminating duplicate messages.
- Chat message template now carries data-task-id so the WS handler
can find and replace the placeholder with the actual response.
- appendMessage() uses DOM APIs (textContent) instead of innerHTML
for safer content insertion before markdown rendering.
- Fixed chat_message.html script targeting when queue-status div is
present between the agent message and the inline script.

The /ws redirect handler crashed with AttributeError because websockets
16.0 removed the legacy transfer_data_task attribute. The /swarm/live
endpoint could also error on early client disconnects during accept.

* fix: resolve portal startup hangs with non-blocking init
- Add socket_connect_timeout/socket_timeout (3s) to Redis connection in
SwarmComms to prevent infinite hangs when Redis is unreachable
- Defer reconcile_on_startup() from SwarmCoordinator.__init__() to an
explicit initialize() call during app lifespan, unblocking the
module-level singleton creation
- Make Ollama health checks non-blocking via asyncio.to_thread() so they
don't freeze the event loop for 2s per call
- Fix _check_redis() to reuse coordinator's SwarmComms singleton instead
of creating a new connection on every health check
- Move discord bot platform registration from lifespan critical path
into background task to avoid heavy import before yield
- Increase Docker healthcheck start_period from 10s/15s to 30s to give
the app adequate time to complete startup

* fix: disable commit signing in git_tools test fixture
The git_repo fixture inherits global gpgsign config, causing git_commit
to fail when the signing server rejects unsigned source context.
Disable signing in the temp repo's local config.

* fix: add dev extras for pip-based CI install
The CI workflow runs `pip install -e ".[dev]"` but after the Poetry
migration there was no `dev` extra defined — only a Poetry dev group.
This caused pytest to not be installed, resulting in exit code 127
(command not found) on every CI run.
Add a pip-compatible `dev` extra that mirrors the Poetry dev group
so both `pip install -e ".[dev]"` and `poetry install` work.

Migrate from Hatchling to Poetry for dependency management, fixing the
Docker build failure caused by .dockerignore excluding README.md that
Hatchling needed for metadata. Poetry export strategy bypasses this
entirely. Creative extras removed from main build (separate service).
Docker changes:
- Multi-stage builds with poetry export → pip install
- BuildKit cache mounts for faster rebuilds
- All 3 Dockerfiles updated (root, dashboard, agent)
Bug fixes from tester audit:
- TaskStatus/TaskPriority case-insensitive enum parsing
- scrollChat() upgraded to requestAnimationFrame, removed duplicate
- Desktop/mobile nav items synced in base.html
- HTMX pointed to direct htmx.min.js URL
- Removed unused highlight.js and bootstrap.bundle.min.js
- Registered missing escalation/external task handlers in app.py

The microservices refactoring (PR #88) accidentally dropped handler
registration, zombie reconciliation, and startup drain from app.py.
Every task entering the queue was immediately backlogged with
"No handler for task type" because self._handlers stayed empty.
Restores the three critical blocks from app_backup.py:
- Register handlers for chat_response, thought, internal, bug_report,
task_request
- Reconcile zombie RUNNING tasks from previous crashes
- Drain all pending tasks on startup before entering steady-state loop
- Re-approve tasks that were backlogged due to missing handlers
Also adds a /ws WebSocket catch-all that accepts stale connections and
closes with code 1008 instead of spamming 403 on every retry, and a
`make fresh` target for clean container rebuilds with no cached state.

The task queue was completely stuck: 82 tasks trapped in pending_approval,
4 zombie tasks frozen in running, and the worker loop unable to process
anything. This removes the approval gate as the default and adds startup
recovery for orphaned tasks.
- Auto-approve all tasks by default; only task_type="escalation" requires
human review (and escalations never block the processor)
- Add reconcile_zombie_tasks() to reset RUNNING→APPROVED on startup
- Use in-memory _current_task for concurrency check instead of DB status
so stale RUNNING rows from a crash can't block new work
- Update get_next_pending_task to only query APPROVED tasks
- Update all callsites (chat route, API, form) to match new defaults

The tasks board and Timmy panel were connecting to /ws which doesn't
exist, causing constant 403 Forbidden rejections and preventing
live event updates from reaching the UI.

Errors and uncaught exceptions are now automatically captured, deduplicated,
persisted to a rotating log file, and filed as bug report tasks in the
existing task queue — giving Timmy a sovereign, local issue tracker with
zero new dependencies.
- Add RotatingFileHandler writing errors to logs/errors.log (5MB rotate, 5 backups)
- Add error capture module with stack-trace hashing and 5-min dedup window
- Add FastAPI exception middleware + global exception handler
- Instrument all background loops (briefing, thinking, task processor) with capture_error()
- Extend task queue with bug_report task type and auto-approve rule
- Fix auto-approve type matching (was ignoring task_type field entirely)
- Add /bugs dashboard page and /api/bugs JSON endpoints
- Add ERROR_CAPTURED and BUG_REPORT_CREATED event types for real-time feed
- Add BUGS nav link to desktop and mobile navigation
- Add 16 tests covering error capture, deduplication, and bug report routes

11 tests verify that the TaskProcessor drains all queued tasks to
completion — the core behavior needed for Timmy's stream of
consciousness. Tests cover: single/batch/burst processing, priority
ordering, mixed task types, failure recovery, timestamp tracking,
and a loop-based inbox zero assertion.
Adds an `isolated_task_db` fixture to functional conftest that gives
each test a fresh temporary SQLite database via pytest's tmp_path.

* feat: add task queue system for Timmy - all work goes through the queue
- Add queue position tracking to task_queue models with task_type field
- Add TaskProcessor class that consumes tasks from queue one at a time
- Modify chat route to queue all messages for async processing
- Chat responses get 'high' priority to jump ahead of thought tasks
- Add queue status API endpoints for position polling
- Update UI to show queue position (x/y) and current task banner
- Replace thinking loop with task-based approach - thoughts are queued tasks
- Push responses to user via WebSocket instead of immediate HTTP response
- Add database migrations for existing tables
* feat: Timmy drains task queue on startup, backlogs unhandleable tasks
On spin-up, Timmy now iterates through all pending/approved tasks
immediately instead of waiting for the polling loop. Tasks without a
registered handler or with permanent errors are moved to a new
BACKLOGGED status with a reason, keeping the queue clear for work
Timmy can actually do.
