feat(gateway): add agents.create/update/delete methods (#11045)

* feat(gateway): add agents.create/update/delete methods

* fix(lint): preserve memory-lancedb load error cause

* feat(gateway): trash agent files on agents.delete

* chore(protocol): regenerate Swift gateway models

* fix(gateway): stabilize agents.create dirs and agentDir

* feat(gateway): support avatar in agents.create

* fix: prep agents.create/update/delete handlers (#11045) (thanks @advaitpaliwal)

- Reuse movePathToTrash from browser/trash.ts (has ~/.Trash fallback on non-macOS)
- Fix partial-failure: workspace setup now runs before config write
- Always write Name to IDENTITY.md regardless of emoji/avatar
- Add unit tests for agents.create, agents.update, agents.delete
- Add CHANGELOG entry
