[luv-12] Default to bypassPermissions in ~/.claude/settings.json (#11)

Add ensure_default_permission_mode() that merges
permissions.defaultMode = bypassPermissions into the user's global
Claude Code settings on each luv run, so new sessions start in bypass
mode instead of the default. Atomic-write, idempotent, no-op on
unreadable/non-dict JSON. Bump version to 0.0.5.
