feat(P06): CoreCI release flow with .coreci.yml and tea integration
- .coreci.yml: 4 pipelines (validate, build, test, release).
Release gated on refs/tags/v*; builds tarball, generates CHANGELOG,
publishes via `tea releases create`.
- scripts/release.sh: standalone wrapper that builds, tars, generates
notes from ---ci--- commit blocks, and publishes via tea. Sources
GITEA_TOKEN from .env if present.
- Makefile: target paths fixed for ldflags injection (cli package path);
added `version`, `changelog`, `release` targets.
- .gitignore: exclude *.tar.gz (build artifacts, regenerated on release).
- CHANGELOG.md: auto-generated from commit log.
Version injection: -ldflags targets internal/cli package vars so
`orca version` reports the correct tag, commit, and build time.
