Change

Report ACP context usage from Penguin's existing per-session telemetry after each turn and from explicitly scoped token events. Preserve exact context-token/window counts, skip missing/unknown/global/malformed values, and leave cost absent when no actual cost data exists. Child history accepts the same typed usage updates.

Depends on #149 (test/acp-windows-producer). No PRs merged.

Validation

Four focused usage/event tests pass on Windows Python 3.11, including Penguin's actual persisted-session usage function and no-global-attribution/invalid-data checks. Ruff and diff checks pass; dedicated ACP CI includes the new test. Previous integrated ACP+native Windows suite:84 passed. Environment suite after portability fix:24 passed.
