* feat(client): publish the TypeScript SDK surface
Make the high-level client API usable for external integrations and document complete agent, workspace, provider, event, and recipe flows.
* fix(client): correlate provider snapshots by daemon cwd
Return the daemon's canonical snapshot identity so waitForReady can match updates for relative, tilde, and otherwise non-canonical paths without duplicating filesystem rules in the SDK.
* test(server): make snapshot cwd assertion portable
* fix(client): gate canonical provider snapshot waits
Older daemons do not expose the canonical snapshot identity needed to correlate workspace updates safely. Require the advertised capability and fail with an update-host message instead of guessing across workspaces.
