Fixes codefori#2741

Changes

• Added support for actions targeting double extensions such as PGM.RPGLE and PGM.CLLE.

How to test this PR

1. Create actions for both RPGLE and PGM.RPGLE.
2. Verify that a file such as foo.pgm.rpgle matches the expected action.
3. Verify that existing single-extension actions still work.

Checklist

• have created one or more test cases
• updated relevant documentation
• Remove any/all console.logs I added
• have added myself to the contributors' list in CONTRIBUTING.md

Summary by CodeRabbit

• Bug Fixes
  • Improved action availability matching for files with multi-part extensions, such as myfile.a.b.
  • Standardized action support checks across the active editor and environment views.
  • Preserved support for global actions, single extensions, and fragment-based matching.
  • Improved handling of editor targets and protected files when determining which actions can run.

📝 Walkthrough

Walkthrough

The change centralizes action target matching in exported helpers. It adds multi-part extension matching and applies the shared logic to action discovery, active editor actions, and environment action execution.

Changes

Action target matching

Layer / File(s)	Summary
Shared availability and extension matching src/ui/actions.ts	getAllAvailableActions now uses isActionAvailable. The new helpers validate action type, protected targets, GLOBAL, fragments, and single- or multi-part extensions.
Active editor target integration src/ui/views/environment/actions.ts	activeEditorChanged derives targets and protected status through uriToActionTarget and uses shared extension matching.
Environment action execution src/ui/views/environment/environmentView.ts	Action execution now uses targetMatchesExtensions for target validation.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 2d830

Double-extension actions may be offered and executed on similarly suffixed but unsupported files. Require a dot-component boundary and add a regression test before merging.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Require an extension-component boundary.

Line 712 matches raw suffixes. For example, foo.XPGM.RPGLE matches an action for PGM.RPGLE. The action can then run against an unintended file.

Match .${ext} and add a regression test for this near-match.

Proposed fix

-      if ((targetDotCount > extDotCount) && targetFile.endsWith(ext)) return true; // match
+      if ((targetDotCount > extDotCount) && targetFile.endsWith(`.${ext}`)) return true; // match

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	if ((targetDotCount > extDotCount) && targetFile.endsWith(ext)) return true; // match
	if ((targetDotCount > extDotCount) && targetFile.endsWith(`.${ext}`)) return true; // match
