Merge pull request 'ci: rename .github/workflows -> .gitea/workflows (post-suspension sweep)' (#5) from ci-rename-github-to-gitea into main

GitHub org Molecule-AI was suspended 2026-05-06; SCM moved to Gitea
(git.moleculesai.app). The wholesale `git push --mirror` migration left
workflow files under .github/workflows/, which Gitea Actions does NOT
read - it reads .gitea/workflows/ exclusively.

This rename + the cross-repo `uses:` path rewrite are the minimum
edits to make CI fire on this repo again. The workflow content itself
is not modified (other than the path rewrites and lowercasing of the
old `Molecule-AI` org reference to the post-suspension `molecule-ai`).

+# Test Rationale — molecule-session-context
+
+## What this plugin does
+
+`molecule-session-context` provides a SessionStart hook (`session-start-context.py`)
+that injects operational context into Claude's context window at session start:
+recent cron-learnings from JSONL, freeze-file status, and open PR/issue counts
+from GitHub.
+
+The hook reads `~/.claude/projects/.../memory/cron-learnings.jsonl` (written by
+`molecule-cron-learnings`) and emits a JSON `additionalContext` payload to stdout.
+It also queries `gh` for repo state and handles graceful degradation when
+`gh` is unavailable or files are missing.
+
+## What is tested
+
+- `hooks/_lib.py` helpers: `read_input`, `emit`, `deny_pretooluse`, `add_context`,
+  `warn_to_stderr`, `get_repo_root`
+- `hooks/session-start-context.py` logic: `tail()` JSONL reader, `gh_count()`
+  subprocess wrapper, full `main()` integration with mocked gh + tempfile learnings
+- Hook error handling (exits 0 on exception, not crash)
+
+## What is NOT unit-tested (and why)
+
+- Real `gh` API calls — tested with `unittest.mock` subprocess interception
+- Actual freeze-file reading — tested with mocked file I/O
+- Integration with the workspace runtime's SessionStart hook harness —
+  requires a real Claude Code session; covered by smoke + integration tests
+
+## Running tests
+
+```bash
+python -m pytest tests/ -v
+```
