Agent Skills: lisa-jira-build-intake

Symmetric counterpart to notion-prd-intake on the JIRA side. Scans a JIRA project (or JQL filter) for tickets in the configured `ready` status, claims the first eligible ticket by transitioning to the configured `claimed` status, runs the implementation/build flow via the jira-agent workflow in-session (culminating in lisa-implement), transitions to the configured `done` status on completion, then exits. Enforces the claim-time arm of the `leaf-only-lifecycle` rule: a parent/container with open child work (or a childless Epic) that still carries a stale build-ready status is skipped or safe-blocked with a lifecycle-repair comment, never claimed. The `ready` status is the human-flipped signal that a TODO ticket is truly ready for development — mirroring how Notion PRDs work product Draft → Ready → (us) In Review → Blocked|Ticketed.
