Hongming Wang ff5f4cbf7c Memory v2 PR-3: built-in postgres plugin server + schema migrations
Builds on merged PR-1 (#2729), independent of PR-2/PR-4.

Implements every endpoint of the v1 plugin contract behind an HTTP
server (cmd/memory-plugin-postgres/) backed by postgres. Operators
run this binary next to workspace-server; it's the default
implementation MEMORY_PLUGIN_URL points at.

What ships:
  - cmd/memory-plugin-postgres/main.go: boot, signal-driven shutdown,
    boot-time migrations, configurable LISTEN/DATABASE/MIGRATION_DIR
  - cmd/memory-plugin-postgres/migrations/001_memory_v2.up.sql:
      memory_namespaces (PK on name, kind CHECK, expires_at, metadata)
      memory_records (FK to namespaces with CASCADE, kind+source CHECK,
                      pgvector embedding, FTS tsvector, ivfflat partial
                      index on embedding, partial index on expires_at)
  - internal/memory/pgplugin/store.go: storage layer using lib/pq
  - internal/memory/pgplugin/handlers.go: HTTP layer (no router dep —
    a switch on URL.Path keeps the binary's dep surface tiny)
  - 100% statement coverage on store.go + handlers.go

Schema notes:
  - These tables live next to the plugin binary, NOT in workspace-
    server/migrations/. When operators swap the plugin, these tables
    become orphaned (operator drops manually). Documented in PR-10.
  - Search supports semantic (pgvector cosine) → FTS (>=2 char query)
    → ILIKE (1-char query) → recent-listing (no query), with a TTL
    filter applied uniformly across all paths.
  - DELETE on namespace cascades to memory_records (FK ON DELETE
    CASCADE) — a deleted namespace immediately frees its memories.

Coverage corner cases pinned:
  - Health: ok, degraded (db ping fails), no-ping fn
  - Every CRUD endpoint: happy path, bad name, bad JSON, bad body,
    not-found, store errors, exec/scan/marshal errors
  - Search: FTS, semantic, short-query (ILIKE), no-query (recent),
    kinds filter, store errors, scan errors, mid-iteration row error
  - Routing edge cases: unknown path, empty namespace, unknown sub,
    method-not-allowed, GET on /v1/health (allowed), POST on /v1/health
    (404), GET on /v1/search (404)
  - Helper internals: marshalMetadata (nil/happy/unmarshalable),
    nullTime (nil/non-nil), vectorString (empty/format),
    nullVectorString (empty/non-empty), scanNamespace +
    scanMemory metadata-decode errors

No callers in workspace-server yet; integration starts in PR-5
(MCP handlers wire the plugin client through to MCP tools).
