* test(perf): render and identity contracts for agent status, sidebar, tab strip and chat
Twelve operation, render and identity contracts at the production seams of
the hottest UI paths, each driven at N and 10N with one hardcoded bound and
shown to fail with its regression restored. Registers them in the contract
list and fixes the perf workflow's path filter, which had drifted to 12 of
19 contracts. Removes test-only production exports nothing reads.
* test(perf): prove composer typing lands; drop dead rebuild counter
Review: the composer contract never checked the draft reached the composer,
and its transcript control could not fail; the live-index rebuild counter
and a bucket constant had no readers after the test exports went.
