runtime: separate broker activity from persistence

[sumitake]

Summary

• Release the public policy/client package as agent-collab 4.5.2.
• Derive selected-lane persistence from a closed live launchctl print
  transcript: exact top-level properties plus structured conditional
  event-trigger evidence, with malformed, incomplete, or ambiguous shapes
  failing closed.
• Report persistent_process=true|false|null independently from the bounded
  point-in-time observation process_idle=true|false|null; null means
  unproven/unmeasured, never false.
• Preserve rolling-upgrade compatibility for consumers receiving the old shape
  without process_idle.
• Keep every mutating lifecycle operation on its existing full-idle boundary
  and prove a failed stage restores the exact baseline selector.
• Pair this change with workspace PR
  https://github.com/sumitake/agent-collab-workspace/pull/2438.

Neither PR is release or activation evidence by itself.

The artifact contains both complete binary diffs with repository-specific path
prefixes and binds every base, head, component size, and component digest.

Boundary declaration

• No provider executor source, raw provider command, credential, private
  absolute path, retired package tree, downloader, or post-install hook is
  included.
• No native-runtime bytes or verification metadata change in this PR.
• The change does not create a host-specific preset or
  provider-specific plugin.

Generated and release surfaces

• Skill and generated surfaces remain in parity.
• Claude and Codex marketplaces/manifests remain in parity.
• Unique changelog.d/ fragment present; generated CHANGELOG.md
  unchanged.
• Version metadata is 4.5.2.

Review and post-condition

Tier 3: this changes the public runtime client's lifecycle/status contract.
Merge workspace PR #2438 first, then this PR. After a separately governed
runtime build and activation, run serial provider-free boundary canaries before
clearing the managed-provider freeze. Retained lane 30 and immutable lane-31
rollback bytes remain untouched.
