memory-router: release 0.7.0

[LanNguyenSi]

Summary

• Cuts memory-router 0.7.0: CHANGELOG Unreleased becomes [0.7.0] - 2026-08-16 with a prominent upgrade note for the model-conditional floor default (measured recall cost; one-line rollback MEMORY_ROUTER_BLEND_MIN_SEMANTIC=0.5 documented in the first Changed bullet); version bump 0.6.0 to 0.7.0 plus lockfile sync. No code changes.
• Ships everything merged since 0.6.0: deterministic directory-walk and comparator ordering (memory-router: sort the three remaining readdir walks deterministically (mm-v1-T005 follow-up) #91-memory-router: consolidate dupes sections on code-unit sorts (last localeCompare removal) #93), lint exit-1 on a rejected topics.yml (memory-router lint: exit 1 on rejected topics.yml (vocabularyError) #94), the loader parse export and drift.ts dedup (memory-router: single shared parse path for loader and consolidate schema-metrics #95, memory-router: drift.ts consumes the loader's frontmatter parse export #99), embed timeout budgets with chunked index rebuilds (memory-router: configurable embed timeout, separate 60s index budget (hook stays 5s) #96), model-conditional floor defaults (memory-router: model-conditional relevance floor defaults #97), the hook-scoped MEMORY_ROUTER_HOOK_EMBED_TIMEOUT_MS knob (memory-router: dedicated MEMORY_ROUTER_HOOK_EMBED_TIMEOUT_MS for the semanticSearch path #100), index-budget chunking for lint --semantic (memory-router: lint --semantic uses the index embed budget and chunks at 64 #103), and the once-per-process floor-drop stderr hint (memory-router: once-per-process stderr hint when an uncalibrated fallback floor drops all semantic candidates #104).

Release plan (after merge)

Tag memory-router-v0.7.0 on the squash commit (pushed alone, per the workflow's coalescing warning) fires publish-memory-router.yml (npm publish with provenance, version-tag match check) and release.yml (GitHub Release from the [0.7.0] CHANGELOG section). Then: npm view @lannguyensi/memory-router@0.7.0, npx dogfood from a neutral cwd (lint exit-1 case + floor-default case, output-asserted against a 0.6.0 negative control), and the mini hook moves to the 0.7.0 binary with the env floor override retired.
