v2.12.2

Changed

• Installer target registry — openltm-core now drives host installation from a shared INSTALL_TARGETS registry, reducing the work to add future agent hosts.
• Shared session prefill — OpenCode, Pi hooks, and the portable Claude bunx hook path now use one core prefill builder, making the "already pre-filled" experience more consistent and honoring a tighter context budget.
• Portable Claude bunx hook — bunx @rohirik/openltm-core hook --name SessionStart now emits a real Prior Knowledge block instead of only printing a stub warning; non-session-start hooks remain safe no-ops.
• Monthly maintenance command — added bun run check:monthly to run tests, typecheck, version sync, dependency audit, and optional local security scanners in one pass.
• Test scope hardening — root bun test now targets the explicit test directories so temporary scripts and Playwright e2e specs do not get executed as accidental Bun tests.

Fixed

• Dependency audit floor — bumped MCP SDK ranges and tightened root overrides for hono, @hono/node-server, body-parser, and qs to clear the current moderate/low audit findings from the monthly maintenance path.
