fix(canary): hash extension files from one read

[100yenadmin]

Summary

• remove the extension-manifest statSync / readFileSync time-of-check/time-of-use pair
• read each file once and derive both bytes and sha256 from the same immutable buffer
• preserve manifest paths, ordering, hash algorithm, and output schema

Proof

• node --check gitnexus/scripts/reconciliation/large-repository-canary.mjs: passed
• git diff --check: passed
• reconciliation-canary-safety.test.ts: 7/7 passed
• promotion PR chore(reconciliation): promote proven RC19 internal source candidate #98 supplies canonical current-head CodeQL and full remote CI after incorporation

Closes #101
Parent: #39
Promotion: #98

This changes only the disposable canary harness. It does not merge promotion, publish, release, deploy, roll out runtime changes, or mutate an index.
