test(#146): clarify t.TempDir() evaluation in subprocess env setup

The previous implementation called os.Lstat(absPath) which only avoids
following the *final* path component. A PR committing .review-bot/ as a
directory symlink pointing outside the repo would pass the filepath.Rel
confinement check because the textual path was inside the root while
the resolved destination was not.

Fix: call filepath.EvalSymlinks after filepath.Abs to resolve ALL symlink
components before the confinement check. If EvalSymlinks fails (dangling
symlink, nonexistent target) the path is rejected. The filepath.Rel check
then operates on the fully-resolved path.

Semantic change: file-level in-repo symlinks (target also within root) are
now allowed — the invariant is about where the content lives, not whether
the entry is a symlink. The test TestValidateDocmapPath_Symlink is updated
to test an out-of-repo symlink target, which must still be rejected.

Tests:
- TestValidateDocmapPath_DirSymlinkBypass: reproduces the attack vector
  (dir symlink bypassing textual confinement check) and verifies it is
  now rejected
- TestValidateDocmapPath_Symlink: updated to test out-of-repo symlink

 ## Unreleased
 
+### Security
+
+- **`validateDocmapPath`: add `EvalSymlinks` to close directory-symlink bypass** ([#150](https://gitea.weiker.me/rodin/review-bot/issues/150)): The previous implementation used `os.Lstat` which only avoids following the *final* path component. An intermediate directory symlink (e.g. `.review-bot/` committed as a symlink to a directory outside the repo) would pass the path-confinement check because the textual path appeared within the repo root. `filepath.EvalSymlinks` is now called first, resolving all symlink components before the `filepath.Rel` confinement check. In-repo symlinks whose resolved targets also reside within the repo root are now allowed; out-of-repo targets are rejected by the confinement check.
+
+### Tests
+
+- **`TestValidateDocmapPath_DirSymlinkBypass`**: verifies that a directory symlink inside the repo pointing outside cannot be used to bypass path confinement ([#150](https://gitea.weiker.me/rodin/review-bot/issues/150)).
+
 ### Added
 
 - **`doc-map` input** (`--doc-map` flag / `DOC_MAP_FILE` env var): Path to a YAML file mapping source path globs to governing design docs. review-bot intersects the map with changed PR paths and injects matching docs into the system prompt under a `## Design Documents` heading. ([#137](https://gitea.weiker.me/rodin/review-bot/issues/137))

-## Coverage Trends
+1. **[IMMEDIATE] Merge 3 ready PRs** (#155 → #152 → #151)
+   - All provide foundational support for downstream features
+   - Safe to merge in sequence; no cross-PR dependencies
+   - Post-merge: dev-loop can run verification cycle

-| llm | 81.3% | 81.3% | → |
-| **Total** | **77.1%** | **70.4%** | **↑6.7%** |
+2. **Schedule AI-review for #156 and #153**
+   - Both feature-complete and test-passing
+   - Waiting on code quality & design review
 
----
+## Cycle Complete ✅
 
-## Recommendations for Next Cycle
-
-### Immediate (This Dev-Loop)
-1. **Checkout #150** — Review symlink fix, run security tests
-2. **Checkout #143** — Review doc-map config fetching, validate error handling
-3. **Decide merge order** — #150 or #143 first (dependency check)
-4. **Run full integration** — After each merge to catch regressions
-
-### Short-term (Next 1-2 cycles)
-- Pull #146 into main if no blockers
-- Merge #154 as low-risk cleanup
-- Check for any test coverage gaps post-merge
-- Monitor for regressions during next run
-
-### Ongoing
-- Continue tracking coverage trend (goal: >80%)
-- Document new security fixes (issue #150)
-- Review CONVENTIONS.md for consistency across new code
-
----
-
-## Worktrees
-
-- All stale worktrees cleaned in previous cycle ✅
-- Ready for new worktree setup if Aaron wants to work on next issue
-
----
-
-## Next Dev-Loop Cycle
-
-When dev-loop runs next (in ~4 hours):
-1. ✅ Verify main still current
-2. ✅ Re-run tests & coverage
-3. ✅ Check if any PRs merged (update local branches)
-4. ⚠️ Flag for human review if coverage drops or tests fail
