Plan M5a: local memory in 15 tasks

memoryd (files, the check, edits, journal, index, recall, serving), the memory tools and built-in grants in brokerd, the memory block in loopd, bxctl reindex and memory, and the device checks with memoryd. Each task was built as a reference and gated. Each was replayed on its own at its end state (854 to 936 tests) and mutation-checked. Each skeleton compiles and fails its tests. Every todo comment was read beside its signature. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
