Cline discovery only looked at the stable VS Code globalStorage root, so
tasks created in VS Code Insiders or VSCodium were never found. The
singular getVSCodeGlobalStoragePath helper returns paths[0], and because
the provider always passed a concrete overrideDir, the 3-variant fallback
inside discoverClineTasks was never reached - unlike the Roo Code and
KiloCode siblings, which pass overrideDir straight through.
Build the default roots from getVSCodeGlobalStoragePaths (stable,
Insiders, VSCodium) plus the ~/.cline/data root and hand them to
discoverClineTasks in one call. The existing dedupe by task id still
collapses a task id seen in more than one root, so totals cannot inflate.
The configuredDirs override used by tests and createClineProvider(dirs)
is unchanged.
