Bo 6b5bebfa12 fix(routing): handle symlinked .beads directories correctly (#1112) ...

When .beads is a symlink (e.g., ~/gt/.beads -> ~/gt/olympus/.beads),
findTownRoutes() incorrectly used filepath.Dir() on the resolved
symlink path to determine the town root.

This caused route resolution to fail because the town root would be
~/gt/olympus instead of ~/gt, making routes point to non-existent
directories.

The fix adds findTownRootFromCWD() which walks up from the current
working directory instead of the beads directory path. This finds
the correct town root regardless of symlink resolution.

Changes:
- Add findTownRootFromCWD() function
- Update findTownRoutes() to use CWD-based town root detection
- Add fallback to filepath.Dir() for non-Gas Town repos
- Add debug logging (BD_DEBUG_ROUTING=1)
- Add comprehensive test case

Test: go test ./internal/routing/...
