This commit removes Jaeger tracing support from the project, including the associated Docker configurations, Go modules, and middleware. The changes simplify the codebase by eliminating unused tracing functionality, which was previously integrated for observability. Documentation and scripts have also been updated to reflect the removal of Jaeger references.
Two unrelated startup-noise fixes bundled because they share one file
(internal/runtime/startup.go) and one motivation (make the boot log
useful again).
Gin per-route spam
------------------
With ~150 registered routes, DebugMode prints one "[GIN-debug] METHOD
path --> handler" line per route, drowning out everything else. Override
gin.DebugPrintRouteFunc to a counter and gin.DebugPrintFunc to route
through the structured logger. A single "[gin] registered N routes"
summary prints once router build is complete. DebugMode behaviour
otherwise (panic recovery, runtime warnings) is preserved.
Env config banner
-----------------
Operators had no easy way to confirm SYSTEM_AES_KEY (or any other
critical env) was actually loaded — getting the byte length wrong is
particularly silent: utils.GetAESKey() returns nil for anything other
than exactly 32 bytes, which simply disables encryption.
LogStartupEnv prints one line per curated env var (security + DB +
storage + redis), with sensitive values redacted as "set (N chars)"
and unset values as "<unset>". Followed by targeted footgun warnings —
the AES-256 length check fires loudly when SYSTEM_AES_KEY is set but
wrong-length.
Both helpers are called from cmd/server and cmd/desktop. The env banner
runs before container.BuildContainer so it prints even if DB / storage
init fails.
