v1.11.0

Fixed

• Refine runs the rewrite guard (#85). Only hindsight called checkRewrite, so refine could drop what a definition committed to or append an observation verbatim, and the signature gate still called the run clean. In one live run, a paper summary was appended to an unrelated memory and its opening "Virgil's memoir-agent idea:" was dropped; another memory lost its closing "(v0.8.1)". Refine now declines both and keeps the old definition. Declined rewrites are counted in phases.refine.declined.
• The guard catches more:
  • Version numbers: the number check now sees them ("v0.8.1" → "0.8.1"; before, \b found no boundary after the v).
  • Dropped named entities: a capitalised word from mid-sentence in the old definition that is gone from the new one.
  • Lost opening subject: the subject the old definition opened with ("Virgil's …") is gone.
  • Growth: with limitGrowth (refine sets it), a definition that grows past max(1.4×, +300 chars) is declined.
  • Case: entity checks ignore case and match whole words, so "Cortex" opening a sentence is not new next to "the cortex API".
• Cluster joins an existing memory only at similarity ≥ 0.75, up from 0.70. A wrong join hands refine unrelated text; a missed join only mints a separate memory. In the run above, the bad join scored 0.712 and the legitimate one 0.797. Set it per namespace with cluster_threshold, which dream and auto-consolidation now pass through.
• Unlabelled abstractions get a real name. With no Pattern: line in the model output, the name used to be the definition's first clause cut short ("The deeper pattern is that systems—whether…"). Abstract now asks deriveName for a concept label, the way create names memories. parseAbstraction returns labelled.
• phases.hindsight.declined is now reported by dreamConsolidate. It was counted but dropped from the result.
