Three upstream Docmost services (export, version, telemetry) require
'../../../package.json' relative to source. In nest start dist mode the
relative path resolves one level too short and crashes at boot.
Wrap each require in a try/catch fallback that walks up one extra level,
defaulting to { version: 'dev' } if neither resolves. Boot now succeeds
both in dev (tsx) and in dist (node dist/main).
Also adds docker-compose.dev.yml for an isolated dev stack on ports
5433/6380, kept in repo for future dev sessions.
Patch 018.
