When a provider (e.g., Google Gemini CLI) requests a retry delay longer
than maxDelayMs (default: 60s), the request fails immediately with an
informative error instead of waiting silently for hours.
The error is then handled by agent-level auto-retry, which shows the
delay to the user and allows aborting with Escape.
- Add maxRetryDelayMs to StreamOptions (packages/ai)
- Add maxRetryDelayMs to AgentOptions (packages/agent)
- Add retry.maxDelayMs to settings (packages/coding-agent)
- Update _isRetryableError to match 'retry delay' errors
fixes#1123
- Add `-path` force-exclude pattern (exact path match, highest precedence)
- Change `+path` force-include to exact path match (no glob)
- Manifest-excluded resources are now hidden from config (not toggleable)
- Config toggle uses `+` to enable and `-` to disable
- Settings paths resolve relative to settings.json location:
- Global: relative to ~/.pi/agent
- Project: relative to .pi
- Add baseDir to PathMetadata for proper relative path computation
- Update tests for new base directory and pattern behavior
fixes#951
