@copilot Check if there are more tests to add.

Added more coverage in ae3ca0e (plus follow-ups 1d93957 and c5f9286): new tests now validate initialize-sqlite-store idempotency and type-check enforcement, and include explicit session-id roundtrip assertions in the idempotency scenario. No UI changes in this PR, so no screenshot applies.

@copilot Check if there are more tests to add, and update the tests that uses the access-session as it now update the last-accessed-at field.

Implemented in 3b0cf43: I added/updated tests around access-session to cover the new last-accessed-at behavior, including a dedicated test that forces stale access timestamps and verifies access-session updates both updated-at and last-accessed-at while preserving session data. No UI changes in this PR, so no screenshot applies.

Implemented in a509c79: I added lifecycle transition coverage in sqlite-store-session-state-transitions, validating create -> active, active -> renewed, active -> expired, active -> terminated, and renewed -> active with explicit assertions using create-session, access-session, renew-session, terminate-session, and session-exists-p. No UI changes in this PR, so no screenshot applies.
