add projects update command

[masnwilliams]

Summary

• Add kernel projects update <id-or-name> command supporting --name (rename) and --status active|archived (archive/reactivate).
• Accepts ID or name as the positional argument (case-insensitive) via existing resolveProjectArg.
• Requires at least one of --name or --status; rejects unknown status values.

Test plan

• make test — unit tests pass (3 new tests covering happy path, missing-flag, bad-status).
• Live test against prod:
  • projects create cli-test-update-flow → success.
  • projects update <id> --name cli-test-renamed → renamed.
  • projects update cli-test-renamed --status archived → archived (resolution by name works).
  • projects update <id> --status active --name cli-test-both → both fields applied at once.
  • projects update <id> (no flags) → error.
  • projects update <id> --status deleted → error listing valid values.
  • projects delete <id> → cleaned up.

Note

Low Risk
Low risk CLI change that adds a new command and corresponding SDK call wiring; main risk is limited to user-facing validation and request parameter construction.

Overview
Adds a new kernel projects update <id-or-name> command to rename projects and/or change their status to active or archived, resolving the identifier via the existing ID/name lookup.

Extends the ProjectsService interface and CLI handler to call the SDK Update endpoint, validates that at least one of --name/--status is provided (and rejects unknown statuses), and prints the updated project details.

Updates tests with a fake Update implementation and adds coverage for the happy path, missing-flags error, and invalid-status error.

Any PR that changes the kernel API. Monitor changes to API endpoints (packages/api/cmd/api/) and Temporal workflows (packages/api/lib/temporal) in the kernel repo

Reason: PR adds a CLI command for projects management, but does not modify API endpoints (packages/api/cmd/api/) or Temporal workflows (packages/api/lib/temporal) as specified in the filter.

lgtm, one minor thing is that if a user tries to enter an empty string for the update, we could check that locally on the CLI, rather than relying on the round-trip to the API.

non-blocking, because it functions the same regardless and create does the same thing
