fix(token-meter): bound projection state via logged shadow prices

The contextBreakdown and contextPressure units carried the full priced
surface, so each session's persisted projection checkpoint grew without
bound. A surface replacement is now priced by the shadow-price event
logged directly before it — compact/summary for compaction, the new
compact/prune from tool-result pruning (priced through the injected
token meter) — and the unit states shrink to a fixed handful of numbers.
Regenerate the persistence/cordis/module/config catalogs.

+ * units deliberately do NOT share this fold — their state must stay O(1)
+ * for the persisted checkpoint, so they ride `surface-projection.ts`'s

+ * both price through `estimate.ts`, and every logged shadow price is derived
+ * from THIS fold's nodes by the replace producer.
