refactor(tests): standardize to node:assert/strict and t.after() per CONTRIBUTING.md (#1675)

* refactor(tests): standardize to node:assert/strict and t.after() per CONTRIBUTING.md

- Replace require('node:assert') with require('node:assert/strict') across
  all 73 test files to enforce strict equality (no type coercion)
- Replace try/finally cleanup blocks with t.after() hooks in core.test.cjs
  and hooks-opt-in.test.cjs per the test lifecycle standards
- Utility functions in codex-config and security-scan retain try/finally
  as that is appropriate for per-function resource guards, not lifecycle hooks

Closes #1674

* perf(tests): add --test-concurrency=4 to test runner for parallel file execution

Node.js --test-concurrency controls how many test files run as parallel child
processes. Set to 4 by default, configurable via TEST_CONCURRENCY env var.
Fixes tests at a known level rather than inheriting os.availableParallelism()
which varies across CI environments.

* fix(security): allowlist verify.test.cjs in prompt-injection scanner

tests/verify.test.cjs uses <human>...</human> as GSD phase task-type
XML (meaning "a human should verify this step"), which matches the
scanner's fake-message-boundary pattern for LLM APIs. This is a
false positive — add it to the allowlist alongside the other test files
that legitimately contain injection-adjacent patterns.
