* fix(#663): resolve open CodeQL/Dependabot security alerts
- ReDoS: collapse ambiguous nested quantifiers in phase-heading regexes
(verify/validate/commands) and the plan-filename lookahead (phase) to
provably-equivalent non-backtracking forms
- prototype pollution: guard __proto__/constructor/prototype in setConfigValue
- remove dead no-op .replace(/-/g,'-') in phase.cts
- escape all regex metachars in bug-2839 test
- add contents:read permissions to security-scan + install-smoke workflows
- pin qs >= 6.15.2 via overrides (DoS GHSA)
- broaden prompt-injection allowlist to translated security-model docs
Closes#663

* test(#663): regression tests for prototype-pollution guard and roadmap-phase ReDoS
Behavioral test that config-set rejects __proto__/constructor/prototype keys
without polluting Object.prototype, plus a ReDoS guard (timing-bound) and
behavior-preservation assertions for the collapsed phase-heading regexes.

* test(#663): make ReDoS regression assert structured result, not elapsed time
Replace elapsed-time assertions (which tripped local/no-elapsed-assertion
ESLint rule and were unsound for synchronous ReDoS) with structured-result
assertions on adversarial inputs: assert that malformed phase headings/
unchecked-item lines without a terminating colon/space yield an empty Set,
which is both the correct behavior and an exercise of the fixed linear regex
on the catastrophic-backtracking input shape.

* chore(#663): add Security changeset fragment for #665

* test(#663): fold prototype-pollution regression into config.test.cjs
The standalone bug-663-config-prototype-pollution.test.cjs was a 9th
config-module test file, tripping lint-test-file-count (the allowlist is
ratcheted and must not grow). Consolidated into config.test.cjs instead.
