fix(security): scorecard job permissions, dispatch secret-gate, .envrc placeholder

[hyperpolymath]

Why

Pre-existing Hypatia workflow_audit findings (unrelated to #28's timeout fix). The 🔴 critical .envrc "Generic API key" is a verified false positive — a commented-out # export API_KEY="..." on line 24 (gitleaks + trufflehog both pass) — and is excluded.

Fixes (3)

1. scorecard.yml — explicit least-privilege job permissions: on the OpenSSF Scorecard reusable-workflow caller (was inheriting top-level read-all, which can't grant the security-events/id-token writes publishing needs). Clears scorecard_wrapper_missing_job_permissions.
2. instant-sync.yml — secret-presence gate on the repository-dispatch step (FARM_DISPATCH_TOKEN mapped to a job-level env var, since secrets can't be referenced directly in if:), so forks skip it instead of firing with an empty token. Clears secret_action_without_presence_gate.
3. .envrc — substitute the unsubstituted {{PROJECT_NAME}} scaffold placeholder with the real project name.

Pending (authorised, follow-up commit)

• governance.yml SHA-pin — governance-reusable.yml@main → a commit SHA (DependencyPinning). Needs the standards@main SHA; standards is out of this session's read scope. Will be added to this branch once the SHA is confirmed.

Not in this PR (riskier / unapproved)

scorecard-enforcer.yml publish-job split (scorecard_publish_with_run_step, non-trivial refactor); setup.sh curl|sh CWE-494 (install-script redesign); codeql.yml "nominal SAST" (its matrix already has language: actions — finding looks stale); GS007 branch cleanup.

Caveats

• instant-sync.yml and scorecard.yml trigger only on push: main / schedule (not on PRs), so their first real execution is post-merge — PR CI validates YAML + the Hypatia scan, not a functional run. Watch the first post-merge Scorecard run for the new job permissions.
