test(launch): verify and publish the first release

[LMLiam]

Goal

Prove the privileged lifecycle and both public installation paths before publishing v0.1.0.

Acceptance criteria

• Record safe starting and final power state.
• Exercise idempotency, quiet output, timers, sleep recovery, and removal.
• Verify Control Centre state and CLI reconciliation.
• Keep the AC Power section unchanged.
• Test public Homebrew and DMG installation from scratch.
• Remove privileged files and leave battery clamshell mode disabled.
• Update the profile README only after the release works.

Owned files

docs/acceptance-test.md, final release documentation, and the LMLiam/LMLiam profile README in its own checkout.

Dependencies

All implementation, release, DMG, and Homebrew issues.

Verification

Run the final verification gate, then repeat both public installation smoke tests.
