v0.7.1

Maintenance release rolling up PRs #36–#46. See CHANGELOG.md for the full entry.

Highlights

• Templates page staleness aligned with attune-author status — switched from file-mtime to content-drift via check_workspace_staleness. Domain narrows to fresh / stale / unknown; very-stale retired end-to-end (route, UI, KPIs, tests). Closes the templates-staleness-alignment spec.
• _editor_dep.py 503-guard removed — attune-rag>=0.1.18 now ships the editor submodule on PyPI, so the guard is dead code. Six lazy require_editor_submodule(...) callsites moved to top-level imports.
• Pin bumps: attune-author[ai]>=0.14.0,<0.15 (required for check_workspace_staleness), attune-rag>=0.1.22,<0.2.
