Run PR validation on release/* branches

[Copilot]

PR validation only ran for main, leaving release branches unprotected from build-breaking PRs.

Changes

• .github/workflows/tools-tests.yml: same addition to both triggers.

on:
  push:
    branches: [ main, release/* ]
  pull_request:
    branches: [ main, release/* ]
