Update checks against registries without a hardcoded token endpoint
(lscr.io and other spec-compliant registries) failed with a blanket
"Check failed" because the manifest HEAD went out anonymously and the
401 was terminal. Parse the Bearer challenge on the 401, fetch a pull
token from the advertised realm, and retry once. Token endpoints that
answer with access_token instead of token are now accepted too.
Fixes#1583.
BREAKING CHANGE: AI Patrol now uses EXACT alert thresholds by default
instead of warning 5-15% before the threshold.
Changes:
- Default behavior: Patrol warns at your configured threshold (e.g., 96% = warns at 96%)
- New setting: 'use_proactive_thresholds' enables the old early-warning behavior
- API: Added use_proactive_thresholds to GET/PUT /api/settings/ai
- Backend: Added SetProactiveMode/GetProactiveMode to PatrolService
- Backend: Added GetThresholds to PatrolService for UI display
- Tests: Updated and added tests for both exact and proactive modes
- Also fixed unused imports in dockeragent/agent.go
When proactive mode is disabled (default):
- Watch: threshold - 5% (slight buffer)
- Warning: exact threshold
When proactive mode is enabled:
- Watch: threshold - 15%
- Warning: threshold - 5%
