Add automatic CI-driven release process (#4)

## Summary - Add CalVer (`YYYY.M.BUILD`) release automation driven by Anvil CI - Modeled after huorn-minecraft's `ci/release.sh` + `.anvil-ci.yml` pattern - On every `main` push, after all checks pass: compute version, build, generate changelog, create Anvil release, tag and push Closes #21 ## Changes - **ci/release.sh** — CalVer version computation from git tags (increment build within month, reset on new month) - **mix.exs** — Version from `$VERSION` env var, defaults to `"0.0.0-dev"` for local builds - **.anvil.yml** — New `release` step after compile/format/dialyzer/test, with branch guard and idempotency check ## Release step workflow 1. Guard: skip if not on `main` 2. Compute version via `ci/release.sh` 3. Idempotency: skip if tag already exists 4. Build with `VERSION` env var 5. Generate changelog from `git log` since last tag 6. Build hex package and docs 7. Create Anvil release with changelog 8. Tag commit and push tag ## Test plan - [x] `ci/release.sh` outputs `2026.4.1` with no existing tags - [x] `ci/release.sh` increments build within same month (`2026.4.1` -> `2026.4.2`) - [x] `ci/release.sh` resets build on month change (`2026.3.5` -> `2026.4.1`) - [x] `mix compile` works without `$VERSION` set (uses `0.0.0-dev`) - [x] `VERSION=2026.4.1 mix eval 'Mix.Project.config()[:version]'` returns correct version - [x] All 547 tests pass, dialyzer clean
