v3.30.1

## What

PATCH release closing #2679 — the statusline generator drift discovered during the v3.30.0 release flow.

## Fix

\`generateStatuslineScript()\` in \`v3/@claude-flow/cli/src/init/statusline-generator.ts\` no longer inlines a 1000-line template string. It now READS \`.claude/helpers/statusline.cjs\` as its single source of truth and substitutes two known values (\`maxAgents\`, \`bakedVersion\`). Every future edit to the helper propagates to \`ruflo init\` output automatically — no manual sync required.

## Impact

- **Fresh installs / re-inits**: get the current v3.29.0-era helper (whole-row-clickable OSC 8, \`(domain)\` suffix, ellipsis on truncation, bright-white bold command styling, 300s cache TTL, \`windowsHide\` on every subprocess spawn) instead of the pre-#2195 non-delegation shape that the generator had frozen at.
- **Existing installs**: unchanged. The deployed helper is already correct; this fix only affects new \`ruflo init\` writes.

## CI

Three static-regression guards updated for the read-and-substitute pattern:
- \`.github/workflows/v3-ci.yml\` — statusline generator delegation smoke
- \`scripts/audit-fix-invariants.mjs\` — #2196 delegation invariant + NEW #2679 sync invariant
- \`scripts/smoke-statusline-generator-delegation.mjs\` — Layer 1 static contract

Each now greps the HELPER for the delegation content (where it now lives) with a paired assertion that the generator still reads it. Drift on either side of the sync is caught.
