Add loadtest/run.pid and loadtest/run.err to .gitignore so k6 runtime
state stops tagging along on git add. Also ignore the orphan /00 file
(stray redirect of pkg/observability/tracing.go) and ROADMAP.md (AI-
synthesised audit doc, not part of the project canon).

Remove compiled binaries (main, terminalShop, api/main, api/api-server)
and server.go.old from git tracking. Add them to .gitignore. Update
README to reflect current project state accurately.
