Engraphis 1.2: time becomes part of recall

Engraphis 1.2 made time a first-class part of memory. The release expanded the compact MCP surface to 30 tools, added world-time and system-time coordinates to recall, and extended the schema so historical code and graph relationships can be inspected instead of flattened away.

What changed

• Temporal recall. Recall and grounded recall expose valid_at for world time and known_at for system time, while writes can set a fact's effective valid_from.
• Schema 5 history. Symbols, code edges, code-memory links, and persisted relationships retain temporal history.
• Explicit mutable claims. Optional subject_key and claim_kind fields make replacement semantics clearer for changing facts.
• Recall quality evidence. Performance reporting, canonical workspace exports, benchmark fixtures, and release-evidence manifests make quality changes reproducible.
• Safer defaults. Supersessions close facts at the replacement's effective world time, non-finite timestamps are rejected, and ordinary recall remains observational by default.
