waxmcp 0.1.39

SPM: from: "0.1.39" on https://github.com/christopherkarani/Wax

Ships the MCP and broker work landed after 0.1.38:

• #188 — hide the daily catalog; keep playbooks in lockstep
• #189 — rebind live sessions, harvest reasons, startup GC
• #190 — recall reports the store it actually used; writes land in the right horizon
• #187 — extract EndedSessionStore from AgentBrokerService
• #191 — drop the disabled GitHub Discussions README link
• Corpus full-text expansion uses DiskEndedSessionStore.withMemory (the openAdhocMemory helper went away in #187)

npm publish is driven by the waxmcp-v0.1.39 tag workflow. Homebrew sha256 is provisional until that workflow finalizes it from the GitHub source tarball.
