#2172: add getIdeMetadataPath() for $IDE_HOME/.ide/<ide>/<workspace>

[quando632]

This PR fixes #2172 (part of #2142)

Foundation step for moving IDE-specific metadata out of the workspace. No behavior change yet.

Implemented changes:

• Added IdeToolCommandlet.getIdeMetadataPath() resolving to $IDE_HOME/.ide/«ide»/«workspace» (reuses IdeContext.FOLDER_DOT_IDE, getIdeHome(), getWorkspaceName()).
• Unit test IdeToolCommandletTest.testGetIdeMetadataPath().
• Changelog entry for the epic Move IDE-specific metada (.idea, .vscode) out of workspace #2142.

The follow-up subtasks switch the actual metadata writers onto this getter: #2173 (JetBrains) and #2174 (VSCode).

Testing instructions

1. cd cli && mvn -Dtest=IdeToolCommandletTest test both tests pass.
2. Verify no existing IDE launch behavior changed (getter is not yet wired into any caller).

Looks good 👍 @quando632: the getIdeMetadataPath() is added as a shared foundation for moving IDE metadata to $IDE_HOME/.ide/«ide»/«workspace», and it’s not wired into any launch path yet, so behavior stays unchanged.

The new unit test covers the path resolution, and the change is ready for the follow-up IDE-specific wiring PRs.
