deb26fbce0 Add debug logging for complete authorization URL 
Shows the exact GET request URL being sent to IndieLogin.com's
/authorize endpoint, including all query parameters in their
encoded form. This helps debug authentication flow issues.

- Added debug log after auth_url construction in initiate_login()
- Logs complete URL with all parameters before redirect
- Version remains 0.9.1 (debugging enhancement only)

ba0f409a2a fix: Add trailing slash to SITE_URL and enhance debug logging (v0.9.1) 
Fix 1: SITE_URL trailing slash normalization
- IndieLogin.com requires client_id URLs to have trailing slash for root domains
- Added automatic normalization in load_config() after env loading
- Added secondary normalization after config overrides (for test compatibility)
- Fixes "client_id is not registered" authentication errors
- Updated redirect_uri construction to avoid double slashes

Fix 2: Enhanced httpx debug logging
- Added detailed request logging before token exchange POST
- Added detailed response logging after token exchange POST
- Shows exact HTTP method, URL, headers, and body for troubleshooting
- All sensitive data (tokens, verifiers) automatically redacted
- Supplements existing _log_http_request/_log_http_response helpers

Version: 0.9.1 (PATCH - bug fixes)
- Updated __version__ in starpunk/__init__.py
- Added CHANGELOG entry for v0.9.1

Tests: 486/514 passing (28 pre-existing failures from v0.8.0)
- No new test failures introduced
- Trailing slash normalization verified in config
- Debug logging outputs verified

5e50330bdf feat: Implement PKCE authentication for IndieLogin.com 
This fixes critical IndieAuth authentication by implementing PKCE (Proof Key
for Code Exchange) as required by IndieLogin.com API specification.

Added:
- PKCE code_verifier and code_challenge generation (RFC 7636)
- Database column: auth_state.code_verifier for PKCE support
- Issuer validation for authentication callbacks
- Comprehensive PKCE unit tests (6 tests, all passing)
- Database migration script for code_verifier column

Changed:
- Corrected IndieLogin.com API endpoints (/authorize and /token)
- State token validation now returns code_verifier for token exchange
- Authentication flow follows IndieLogin.com API specification exactly
- Enhanced logging with code_verifier redaction

Removed:
- OAuth metadata endpoint (/.well-known/oauth-authorization-server)
  Added in v0.7.0 but not required by IndieLogin.com
- h-app microformats markup from templates
  Modified in v0.7.1 but not used by IndieLogin.com
- indieauth-metadata link from HTML head

Security:
- PKCE prevents authorization code interception attacks
- Issuer validation prevents token substitution attacks
- Code verifier securely stored, redacted in logs, and single-use

Documentation:
- Version: 0.8.0
- CHANGELOG updated with v0.8.0 entry and v0.7.x notes
- ADR-016 and ADR-017 marked as superseded by ADR-019
- Implementation report created in docs/reports/
- Test update guide created in TODO_TEST_UPDATES.md

Breaking Changes:
- Users mid-authentication will need to restart login after upgrade
- Database migration required before deployment

- Homepage with recent published notes
- Note permalinks with microformats2
- Server-side rendering (Jinja2)

**Admin Routes**:
- Login via IndieLogin
- Dashboard with note management
- Create, edit, delete notes
- Protected with @require_auth decorator

**Development Authentication**:
- Dev login bypass for local testing (DEV_MODE only)
- Security safeguards per ADR-011
- Returns 404 when disabled

**Templates & Frontend**:
- Base layouts (public + admin)
- 8 HTML templates with microformats2
- Custom responsive CSS (114 lines)
- Error pages (404, 500)

### Bugfixes (v0.5.1 → v0.5.2)

1. **Cookie collision fix (v0.5.1)**:

   - Update route now returns 404 for nonexistent notes
   - Delete route now returns 404 for nonexistent notes
   - Follows ADR-012 HTTP Error Handling Policy
   - Pattern consistency across all admin routes

3. **Note model enhancement (v0.5.2)**:
   - Exposed deleted_at field from database schema
   - Enables soft deletion verification in tests
   - Follows ADR-013 transparency principle

### Architecture

**New ADRs**:
- ADR-011: Development Authentication Mechanism

- ADR-013: Expose deleted_at Field in Note Model

**Standards Compliance**:
- Uses uv for Python environment
- Black formatted, Flake8 clean
- Follows git branching strategy
- Version incremented per versioning strategy

### Test Results
