ldgr-core v0.1.12

LDGR Core 0.1.12 improves dependency-oriented planning and schedule inspection.

Highlights:

• Work list and detail output now includes dependency satisfaction, dependents, effective readiness, and blocker reasons.
• Individual dependency edges can be added or removed without recreating work items.
• New human-readable, JSON, filtered, and Mermaid graph output makes schedule structure visible.
• New schedule audits flag graph structure problems, canceled dependencies, priority inversions, terminal reachability, and missing validation records.
• Schedule imports support transactional dry-runs, and example schedule JSON can be exported directly.
• Full JSON status identifies the enriched queue and any pending work decision.
• run finish now explains the pending-decision state and prints the required follow-up command.
