ci: retire dormant reborn-integration workflow, add Reborn suites to nightly deep CI

[serrrfirat]

Summary

• Delete .github/workflows/reborn-integration.yml: it only triggered on the dormant reborn-integration branch, so it has not run for any main-targeted work. Its three jobs (Reborn crate-family package matrix, per-crate tests, 4-partition root parity tests) are byte-for-byte duplicates of what reborn-tests.yml already runs on every PR, merge queue entry, and main push — retiring it loses no coverage.
• Drop the stale reborn-integration.yml entry from scripts/ci/classify-test-scope.sh.
• Add the Reborn suites to Nightly Deep CI: previously nightly only called the legacy test.yml, so the Reborn binary had no scheduled safety net. Wires in reborn-tests.yml (per-crate tests + root parity partitions; scope detection short-circuits to full scope for non-PR events) and reborn-e2e.yml (deterministic Rust contract gate + gateway and WebUI v2 Playwright smoke; workflow_call bypasses the PR path filters so the full gate runs).
• The existing nightly alert job now opens/updates its failure issue if any of the three suites fails (combined-result expression); failed-job logs flow through unchanged since reusable-workflow jobs belong to the caller's run.

Change Type

• Bug fix
• New feature
• Refactor
• Documentation
• CI/Infrastructure
• Security
• Dependencies

Linked Issue

None.

Validation

• cargo fmt --all -- --check — N/A, no Rust changes
• cargo clippy --all --benches --tests --examples --all-features -- -D warnings — N/A, no Rust changes
• cargo build — N/A, no Rust changes
• Relevant tests pass: bash scripts/ci/test-classify-test-scope.sh (all cases PASS)
• cargo test --features integration — N/A, no database-backed behavior changed
• Manual testing: python3 yaml.safe_load parses the edited workflow; grep -r reborn-integration confirms no remaining workflow/script references (docs mentions are historical plan documents)
• Both Reborn workflows already declare workflow_call with a ref input and use inputs.ref || github.sha in every checkout, need no secrets, and pass today on every Reborn PR — same reuse pattern Nightly Deep CI already uses for test.yml

Not verified live: an actual scheduled nightly dispatch. workflow_dispatch on nightly-deep-ci can dry-run it after merge.

Security Impact

None. permissions: contents: read unchanged; the alert job's existing scoped permissions are untouched.

Reborn Trust-Boundary Checklist

N/A — CI workflow wiring only, no Rust/runtime/DB changes.

Database Impact

None.

Blast Radius

CI only: Nightly Deep CI workflow, scope-classifier shared-path list, and removal of a workflow that never ran on main-targeted refs. No PR-gating or merge-queue behavior changes.

Rollback Plan

Revert the single commit — restores reborn-integration.yml and the previous nightly job set.

📝 Walkthrough

Walkthrough

Nightly deep CI workflow integrates Reborn tests as mandatory gates by adding reborn-tests and reborn-e2e jobs and updating alert aggregation to require success across all three test suites. Legacy reborn-integration.yml references are removed from CI scope classification.

Changes

Consolidate Reborn Tests into Nightly CI

Layer / File(s)	Summary
Nightly workflow augmentation with Reborn test gates .github/workflows/nightly-deep-ci.yml	New reborn-tests and reborn-e2e jobs call reusable Reborn workflows; nightly-alert now depends on all three test suites and computes ALERT_RESULT as success only when deterministic-deep-tests, reborn-tests, and reborn-e2e all report success.
Legacy workflow reference cleanup scripts/ci/classify-test-scope.sh	Scope classifier pattern excludes .github/workflows/reborn-integration.yml from shared test paths.

🔄 Three gates now dance in sync,
Nightly vigil guards the brink,
Old pipelines fade to black,
One strong flow takes the track. ✨
