Fix: volume mount tilde expansion, PR counting bug, startup diagnostics

- docker-compose: use ${HOME}/.timmy instead of ~/.timmy (Docker doesn't expand tilde)
- exporter: start HTTP server BEFORE first collection (so /metrics is always available)
- exporter: add startup diagnostics (data dir check, Gitea reachability)
- exporter: fix agent PR counting that would crash on _value access
