docs(backup): correct backup/.backup/.backupignore docs across the system
Streamlined prompts had drifted from reality. Full-context investigation
(3 agents + @memory storyline) corrected:
- .backup/ documented as a SHARED runtime namespace (3 writers: @backup
snapshot stores, @memory rollover safety copies, @flow processed_plans),
not @backup-exclusive.
- @backup README: full 11-command coverage, .backup/ store layout, and a
.backupignore (gitignore-for-backups: pathspec/gitwildmatch, BUILTIN_IGNORES,
self-exclusion, ships as config) section.
- @backup branch prompt: stale .backup_system/ -> .backup/ (3x), drive_test.py
-> drive_check.py (was misleading the agent every turn).
- Root README: @backup added to roster + uninstall covers .backup/.backupignore.
navmap @backup line corrected (Drive planned + shared namespace).
- Shipped root /.backupignore realigned to BUILTIN_IGNORES (dropped stale
.backup_system/, removed over-broad *logs).
- Removed dead backup/run/ test dir.
@backup verified: 220 tests green, seedgo 100%. Closes td-218.
