v0.1.0 shipped two bugs that left /healthz returning 200 against a
half-loaded bundle: the path-repo symlink dangling at runtime in the
AppImage (vendor/php-qml/bridge → nonexistent), and the writable
cache-dir bug (Symfony couldn't create var/cache/prod). HealthController
returned a static {status:"ok"} without ever touching any BridgeBundle
service, so perfsmoke + the connection-state probe both passed even
when the bundle's autoload was broken — first sign of trouble was a
500 from /api/todos under real load.
Inject Publisher (the bundle's Mercure-publish wrapper) via constructor
and reference its FQN in the response body. Two effects:
- Symfony's container resolves Publisher when the controller is
instantiated; if the bundle's autoload is broken, the controller
can't even construct, /healthz returns 500.
- The response now includes `bundle: "PhpQml\Bridge\Publisher"` —
proves to perfsmoke + dev console that the canary is live, not a
cached static response.
Connection-state probe semantics unchanged: still 200 = Online,
non-200 = Reconnecting/Offline. Probe interval is 5s — Publisher's
construction is constant-time, no perf concern.
No new public API: /healthz response gained a `bundle` field
(additive, JSON parsers ignore unknown keys); 200 vs 500 boundary is
preserved. No existing consumer broken.
