Configure workflows to run on merge queue and fix CLA for copilot PRs

[Copilot]

The CI workflows needed to be configured to run e2e tests in the merge queue (not on every PR) while maintaining validation on PRs, with concurrency limits and without cron scheduling. Additionally, the CLA workflow needed to be updated to exclude copilot agent authored PRs.

Changes

claude-code-test.yml (e2e tests):

• Removed pull_request trigger entirely
• Now runs only on workflow_dispatch (manual) and merge_group (merge queue)
• Removed schedule cron trigger (was running weekly on Mondays)
• Simplified claude-code-e2e job condition to check for workflow_dispatch or merge_group events
• Concurrency controls: cancel-in-progress: true ensures new commits cancel running tests

validate.yml:

• Added merge_group trigger in addition to existing pull_request trigger
• Ensures validation (formatting, linting, tests) runs both on PRs and in merge queue

cla.yml:

• Added copilot-swe-agent[bot] to the CLA allowlist
• Prevents CLA checks from failing on copilot agent authored PRs

Result

claude-code-test.yml workflow:

• Runs only in merge queue or via manual dispatch (not on PRs)
• Reduces API usage by not running e2e tests on every PR commit
• Validates code before merging to main

validate.yml workflow:

• Runs on PRs for quick feedback
• Also runs in merge queue for final verification before merge
• Cancels in-progress runs when new commits are pushed

cla.yml workflow:

• Automatically skips CLA signature checks for bot accounts including copilot-swe-agent[bot]

# claude-code-test.yml
on:
  workflow_dispatch:
  merge_group:

# validate.yml  
on:
  pull_request:
  merge_group:

# cla.yml
allowlist: 'dependabot[bot],github-actions[bot],claude,copilot,copilot-swe-agent[bot]'

Original prompt

make it so that the e2e ci tests run on each PR that is ready for review (as opposed to draft). Make sure that there are concurrency limits too so that we kill any running test if the branch updates and a new instance starts. Also make sure that it is running only on the PR and not when the PR merges. Remove any cron triggers it might have

@copilot - update the CLA github action so that it does not apply to copilot agent authored PRs (like this one that is failing that check).

Done in ed3eee3. Added copilot-swe-agent[bot] to the CLA allowlist so the CLA check will skip copilot agent authored PRs.
