test: Remove duplicate killWithTimeout tests (#2870)

* test: remove duplicate and theatrical tests

- cmd-fix-cov.test.ts: remove 6 duplicate fixSpawn tests already covered
  in cmd-fix.test.ts; keep only the unique success message assertion
- icon-integrity.test.ts: consolidate 54 per-entity it() blocks into 4
  data-driven tests (same 67 expect() calls, 50 fewer test cases)
- manifest-type-contracts.test.ts: consolidate per-field for-loop it()
  blocks into 3 grouped tests (same 662 expect() calls, 15 fewer cases)

* test: remove duplicate killWithTimeout tests from ssh-cov.test.ts

The `killWithTimeout additional` describe block in ssh-cov.test.ts
duplicated scenarios already covered in kill-with-timeout.test.ts:
- "sends SIGTERM then SIGKILL" == kill-with-timeout's SIGKILL grace test
- "does nothing when first kill throws" == kill-with-timeout's SIGTERM throw test

Removed the 2 duplicate tests from ssh-cov.test.ts. The dedicated
kill-with-timeout.test.ts file is the canonical location for
killWithTimeout coverage.
