fix: resolve portal startup hangs with non-blocking init (#93)

* 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.
