* fix(config): prevent AJV schema defaults from leaking into persisted config
Fixes#56772. Ensures that channel and plugin AJV validations respect the applyDefaults option, preventing runtime defaults from being written to openclaw.json during doctor/update flows.
* test: address review feedback on #56772 fix
- Split validation.channel-metadata.test.ts into applyDefaults true/false cases (fixes CI)
- Update io.write-config.test.ts regression test to use a mock plugin registry, ensuring it actually exercises the AJV default injection path
* fix(config): revert applyDefaults passthrough to prevent required-field regression
Codex-connector correctly identified that BlueBubbles channel schema marks
enrichGroupParticipantsFromContacts as both default:true and required.
Passing applyDefaults:false during write validation would cause required
checks to fail, breaking writeConfigFile entirely.
Reverted validation.ts to always use applyDefaults:true for channel/plugin
AJV validation. The protection against default leakage into persisted config
is fully handled by the persistCandidate change in io.ts (cfgToWrite uses
the pre-validation merge-patched value, not validated.config).
Updated validation.channel-metadata.test.ts to reflect this architecture.
* fix(config): apply legacy web-search normalization to persistCandidate
* fix: stabilize config default-leak landing tests (#56834) (thanks @openperf)
