feat(style): Fix 1-space indentation in 27 files

Files corrected:
- src/fuzzy_anchor.py (18 violations)
- src/patch_modal.py (14 violations)
- scripts/extract_symbols.py (4 violations)
- scripts/tasks/download_fonts.py (8 violations)
- tests/: 23 files with indentation issues

All files verified with py_compile. Remaining 4 files
(test_api_events.py, test_discussion_takes_gui.py,
test_gui_updates.py, test_headless_service.py) have complex
multi-line with statements that require manual correction.
