v0.9.0 — loopuccino update: drift diagnosis and self-update for checkout installs

Added

• loopuccino update: reports drift between the installed CLI, the checkout, the latest GitHub release, and the skill wiring; --apply pulls the checkout, reinstalls the CLI, and re-verifies with the new binary. The GitHub check degrades gracefully offline, wiring-only findings prescribe loopuccino install commands instead of a misleading --apply hint, and update is documented as the only command that uses the network, Git, or a shell.

Changed

• Execution tier polish from the 0.8.0 release review: the harness adapter clarifies that the coordinator's declared tier constrains which session runs the loop; a verifier is declared as its own named worker group; the card template's durable note clearly replaces both role lines; and the template pin test asserts the tier slot tokens.
