Pull request overview

Removes Copilot Code Review (CCR)-specific branching from the CodeQL Action and cleans up associated tests and PR-check infrastructure, aligning “managed/dynamic” workflow handling with the remaining supported modes.

Changes:

Delete CCR detection (isCCR) and related test helpers/tests.
Simplify feature-flag initialization to only use offline defaults when not running on GitHub.com (e.g., GHES), and adjust tests accordingly.
Remove CCR PR-check template/workflow and update the PR template wording to reflect current managed workflow products.

Show a summary per file

File	Description
src/testing-utils.ts	Removes the CCR test helper (mockCCR) and its now-unused import.
src/feature-flags/offline-features.test.ts	Updates offline-features test setup to simulate non-dotcom (GHES) instead of CCR.
src/feature-flags.ts	Removes CCR-specific offline feature-flag path in initFeatures.
src/feature-flags.test.ts	Removes the CCR-specific initFeatures test.
src/config-utils.ts	Switches “ignore generated files” gating from CCR to dynamic workflows; updates comment (needs follow-up).
src/actions-util.ts	Removes CCR detection and makes isDefaultSetup() equivalent to isDynamicWorkflow().
src/actions-util.test.ts	Removes CCR test; leaves a now-misleading env var setup in the default-setup test (needs follow-up).
pr-checks/checks/ccr.yml	Removes the CCR pr-check definition.
.github/workflows/__ccr.yml	Removes generated CCR workflow (generated file; not reviewed).
.github/pull_request_template.md	Updates risk assessment checklist/options to remove CCR references and add “Development/testing only”.
lib/*.js	Generated output updates corresponding to src changes (not reviewed).

The comment says "in a dynamic workflow or the corresponding FF is enabled", but the condition actually requires both: IgnoreGeneratedFiles must be enabled and isDynamicWorkflow() must be true. Update the comment to match the logic (or adjust the condition if the intent really is an OR).

This is true, and I am pretty sure we had this on the PR that introduced it, and just like then I am not sure I want to re-run all CI for it 😆

🫡

Change of behaviour, but should be safe since this FF isn't rolled out yet.

Yeah, it's not rolled out. We also know since merging that feature that it may be more widely useful, so it makes sense to widen the condition here while we are at it.
