v0.7.0 — Retrieval-first context + memory substrate

Added

• pmctl context query --source memory — memory cards are now searchable alongside repo content; context index covers both planes
• pmctl memory doctor — validates memory card frontmatter, detects stale/superseded/archived cards, reports shard counts
• pmctl memory shard + pmctl memory rebuild-summary — episode archiving and monthly summary rebuild
• /mem-recall step 2b — pmctl context query --source memory retrieves related past episodes before reply
• /mem-distill step 2b — triggers rebuild-summary + shard on distillation
• pmctl artifacts list — lists dispatch run artifacts with metadata
• pmctl pre-release audit <milestone-id> — structural pre-release audit: PR refs, CHANGELOG coverage, body residuals, index/body status (Layer 1 + Layer 3 blind-spot declaration)
• scripts/release-verify.sh Phase 3c — v0.7.0 feature smoke (memory-source · doctor · artifacts · pre-release)

Changed

• MEMORY.md injection now uses usage-based frecency ranking (Firefox bucket + W-TinyLFU + keyword tier); priority: always pins to top
• Lifecycle validity gate: stale/superseded memory cards are deprioritised in injection ranking; priority: always bypasses gate
• Episode summaries use newest-first ordering via pmctl memory rebuild-summary

Fixed

• install.sh now passes PM_DISPATCH_REPO="$REPO_ROOT" per-call to install-guards.sh, preventing ambient env override from breaking spaced-path and MSYS symlink installs
