Conflict resolution: keep M3's full handler.go rewrite (per-stream
index, error matrix, PATCH, CORS, auto-cleanup) and re-apply the
swagger annotations from #7 onto the new function declarations,
including a fresh annotation for the M3-introduced Trickle endpoint.
Swagger docs regenerated to pick up all three.
Race-clean: go test -race ./app/webrtc/... green.
The WHEP routes were mounted by http/server.go via the app/webrtc
Handler.Register(), but Subscribe and Unsubscribe carried no swag
annotations. The Swagger UI at /api/swagger/index.html therefore
didn't list /api/v3/whep/* — programmatic API consumers and humans
browsing the docs couldn't discover the endpoints.
Adds the standard upstream-shaped @Summary / @Tags / @ID / @Router
annotations on Subscribe and Unsubscribe (matching the rtmp.go and
srt.go pattern) and regenerates docs/{docs.go,swagger.json,swagger.yaml}
via 'make swagger'. Verified: swagger.json now contains both paths,
swagger UI renders them under the v16.16.0 tag.
Closes#3.
