* docs: add implementation plan for max conn limit
* feat: add CLimiters support for websocket reporter
* feat: add max_conn field to user and forward models
* feat: implement max conn limiter dispatching
* feat: add maxConn to user and forward CRUD API
* feat: add max conn UI to user management and forward rules
* fix: load MaxConn in get forward record and add e2e contract test for max conn limit
- Normalize whitespace in error messages to handle collapsed variants (e.g., 'address alreadyin use')
- Delete all forward service name variants (_tcp, _udp, base) during cleanup instead of stopping after first success
- Add comprehensive test coverage for edge cases
When tunnel services encounter 'address already in use' errors during
creation/update, automatically cleanup and retry once instead of failing
immediately. This handles race conditions during rapid tunnel reconfiguration.

* fix: tolerate service not found during forward deletion
- Refactor deleteForwardServicesOnNode to handle not-found errors gracefully
- Extract deleteForwardServiceCandidates helper for reuse
- Add tests for not-found tolerance scenarios
- Ensures compatibility with legacy node versions

* fix: add forward port occupancy validation and runtime residual cleanup
- Add forward port occupancy validation on create/update paths
- Extend self-occupy recovery to clean residual candidate service names
- Add regression tests for address-in-use recovery with legacy runtime residue
Fixes port conflict issues when upgrading from 2.1.6 to later versions

When upgrading from older versions, service names changed from
placeholder IDs (forward_user_0) to real user_tunnel IDs, causing
service not found errors during control operations.
- Add fallback cleanup+rebuild logic on UpdateService when service
not found during the upgrade transition period.
- Add self-healing retry on Pause/Resume when all variants are missing.
- Refactor controlForwardServicesOnNode to support unit testing.
- Add tests for shouldSelfHealForwardServiceControl and
controlForwardServiceCommand helper functions.

- Move user tunnel resolution before building service base name
- Add buildForwardServiceBaseWithResolvedUserTunnel helper
- Ensure service names carry the actual user_tunnel ID instead of 0

When a forward service is updated with a bind IP that doesn't exist on the
host network interfaces, the system now automatically falls back to the
default bind address (listening on all interfaces) instead of failing.
- Added syncForwardServicesWithWarnings to collect fallback warnings
- Implemented fallbackForwardPortToDefaultBind for graceful degradation
- Added UpdateForwardPortBindIP repository method to persist fallback
- Enhanced error detection for 'cannot assign requested address' errors
- Frontend displays warning toasts when fallback occurs
- Added comprehensive unit tests for new error detection functions
When UpdateService encounters bind address conflicts (port already in use),
the handler now automatically deletes existing forward services and retries
the AddService operation. This resolves issues where a forward's own stale
listener prevents the update.
- Add isBindAddressInUseError() to detect port bind conflicts
- Add rebindForwardServiceOnSelfOccupiedPort() for automatic cleanup and retry
- Add HasOtherForwardOnNodePort() repository method to verify port ownership
- Add unit tests for bind conflict detection
- Pass connectIp through resolveChainProbeTarget in diagnosis stream start items
- Pass connectIp in appendChainHopDiagnosis for full chain probes
- Reconstruct tunnel state with connectIp field preserved
- Fix forward service config when bindIP already contains port
- Add contract tests for connectIp diagnosis scenarios
- Add unit test for bindIP with port in buildForwardServiceConfigs
- Update AGENTS.md with plan document rules
Entire-Checkpoint: 35a2e61c2431
* feat: add comprehensive migration test for legacy columns
- Add ExtraIPs, TCPListenAddr, UDPListenAddr to Node migration
- Add ip_preference to Tunnel migration
- Add test for very legacy database migration (1.x schema)
- Include issue #211 tracking document
