v0.12.0

Native OMP runtime support and instant delivery.

Added

• Optional remarc-wake extension with explicit /remarc-pair and /remarc-unpair, managed lifecycle timers, session-scoped watching, and next-turn delivery.
• Versioned OMP lease with token/PID/heartbeat ownership, atomic cross-marker claims, stale-owner fencing, owner-token cleanup, and a durable retry outbox.
• Native OMP session creation and origin: "omp" across the MCP runtime, shared schema, cross-language fixtures, workflow skill, and installed-runtime smoke tests.
• Adversarial coverage for lock contention, unsafe paths, competing owners, branch/session transitions, lease expiry, generation ordering, payload limits, crash replay, and bounded shutdown.

Changed

• Public integration version is 0.12.0; MCP implementation version is 0.3.0.
• Shared wake selection and marker serialization are now forward-compatible modules used by Claude Code and OMP.
• OMP creation trusts only the OMP-owned server identity, leaves the legacy session-id field empty, and writes no ownerless historical marker.
• CI exercises exact OMP 17.3.4 core and wake install, discovery, enable/disable, uninstall/reinstall, and cached-package behavior.

OMP core MCP access remains compatible with Remarc 1.0.1. Native OMP badges and instant delivery require Remarc 1.1.0 or later.
