Console command bridge:doctor surfaces actionable hints for env / wiring
problems so first-run failures aren't a "connection refused" mystery.
Checks PHP version, ext-curl, ext-json, the Publisher service is wired
(meaning BridgeBundle loaded), and the BRIDGE_TOKEN / MERCURE_URL /
MERCURE_PUBLISHER_JWT_KEY / MERCURE_SUBSCRIBER_JWT_KEY env vars. With
--connect, also probes the configured URL via plain stream context (no
extra dep) and fails the run when unreachable.
CommandTester suite covers green path, missing-env path, and an
unreachable-URL probe — 11 tests, 32 assertions, all green.
Skeleton's Makefile target stays a TBD until sub-commit 6 stands up the
Symfony app the command runs from.
