Clean up remaining dead code and dependencies

- Replace unused 'codemirror' barrel dep with explicit @codemirror/{state,
  view,commands,language} sub-packages that were imported but unlisted
- Remove unused exports: writeNamespacedQuery, targetWorkspacePathForRun,
  isWorkspaceDeletionRun, piWebConfigDir, duplicate parsePiWebRuntimeResponse
- Remove unused types: WorkspacePanelFiles, WorkspacePanelHost,
  GetActiveSession, SaveAttachmentsResponse, QueryValues
- Drop now-unused re-exports/imports cascading from the above
- Add knip config + 'npm run knip' script for ongoing dead-code detection
