[AI] Add getNote and updateNote to public API #2664

	# When the "unfreeze" label is added to a PR, add that PR to Merge Freeze's unblocked list
	# so it can be merged during a freeze. Uses pull_request_target so the workflow runs in
	# the base repo and has access to MERGEFREEZE_ACCESS_TOKEN for fork PRs; it does not
	# checkout or run any PR code. Requires MERGEFREEZE_ACCESS_TOKEN repo secret
	# (project-specific token from Merge Freeze Web API panel for actualbudget/actual / master).
	# See: https://docs.mergefreeze.com/web-api#post-freeze-status
