Bug: Chat Participant Registration Before Client Activation

A race condition exists where the chat participant is registered before the language client is activated. The chat participant's handler calls getClient().sendRequest(), which requires an initialized language client. Since registerPomlChatParticipant() is called before activateClient() in extension.ts, attempts to use the chat participant before the language server is ready will fail due to an uninitialized client.

Bug: Uri Handling and Template Resolution Errors

The chat participant has two issues:

It attempts to call fsPath on vscode.Uri references that may not be file URIs (e.g., http, https), leading to errors. The current filtering only validates Uri instance type, not file scheme.
The chat.poml template file is incorrectly resolved relative to context.extensionUri. The gallery folder is at the repository root, making the file inaccessible when the extension is packaged.

             files: files.map(f => f.fsPath),
