* fix(security): restore permissions: {} on publish + release-candidate workflows

These two release-publishing workflows had permissions: {} (the strictest valid form) before PR #1454, which replaced it with permissions: read-all. Every job in both files already declares its own permissions block, so the workflow-level default is only the safety net for future jobs added without one — read-all weakens that net for no benefit. Restore {} and the explanatory comment.

Scorecard's TokenPermissions check accepts both forms, so this preserves U9 compliance.

* fix(security): narrow permissions: read-all to contents: read on 13 workflows

PR #1454 added permissions: read-all to 13 workflows that previously had no top-level permissions block. read-all is Scorecard-compliant but unnecessarily broad — every job in scope only needs contents:read at the workflow level (job-level blocks already grant the writes that any job actually performs).

Snapshot of every job in the 13 workflows confirms contents:read is sufficient:

- ci.yml: quality/tests/scope-parity have explicit contents:read job blocks; save-pr-meta uses upload-artifact only (no token scopes needed); ci-status is pure shell.
- ci-e2e.yml, ci-quality.yml, ci-scope-parity.yml, ci-tests.yml: all jobs do checkout + npm + tsc/vitest/playwright/upload-artifact only; no API token scopes required.
- claude.yml, codeql.yml, dependency-review.yml, docker.yml, gitleaks.yml, pr-labeler.yml, trivy.yml, workflow-lint.yml: all jobs already declare their own job-level blocks (security-events:write, pull-requests:write, packages:write, etc.) so the workflow-level default does not gate them.

zizmor (--min-severity high) is clean on the resulting tree. Pre-existing medium findings (secrets-inherit, artipacked) are in unrelated workflows and untouched by this commit.

scorecard.yml also uses read-all but pre-existed PR #1454 and is deferred to a follow-up PR per the plan's scope boundary.
