Default commands missing fix.

[GollyJer]

Fixes missing default commands in TUI.

Greptile Summary

This PR fixes missing default commands in the TUI by correcting how slash commands are collected and resolves TypeScript declaration issues.

Key Changes

• dialog-command.tsx: Fixed slashes() method to use the new slash field on CommandOption objects instead of filtering by "/" prefix in values. The method now uses flatMap to filter commands with the slash property and returns proper slash command objects with display names, aliases, and onSelect handlers.
• custom-elements.d.ts files: Replaced broken symlinks in packages/app and packages/enterprise with actual TypeScript declaration files containing export {} to satisfy TypeScript module requirements.

Root Cause

The original slashes() implementation filtered options by checking if value.startsWith("/"), but the actual command values don't have "/" prefixes (e.g., "session.list", "model.list"). The "/" prefix was only meant for display purposes. Commands now properly declare slash command metadata via the slash field, which includes the command name and optional aliases.

Confidence Score: 5/5

• This PR is safe to merge with no identified risks
• The changes are straightforward bug fixes with clear logic improvements. The slashes() method now correctly uses the slash field as intended by the architecture, and the TypeScript declaration files properly replace broken symlinks. All commands with slash fields in app.tsx will now be correctly returned.
• No files require special attention
