feat(vscode): experimental CLAUDE code migration

[WebReflection]

What Problem This Solves

Global Claude Code configuration has no controlled path into Kilo. Compatibility fallback can also leave global Claude and Kilo instructions or skills active at the same time.

Why This Change Was Made

This adds an opt-in, one-time migration for the supported global Claude Code subset:

• Imports global CLAUDE.md, standalone skills, and top-level MCP definitions only.
• Uses a receipt and global config lock to guarantee one attempt with no automatic retry.
• Preserves Claude source files byte-for-byte and never deletes them.
• Skips unsupported syntax, symlinks, bundles, conflicts, unsafe destinations, and custom routing contexts.
• Preserves literal MCP values while importing all MCP servers disabled.
• Keeps existing Kilo instructions, skills, commands, and MCP names authoritative.
• Stops automatic global Claude fallback after the migration attempt while preserving project-level Claude compatibility.
• Reports complete, partial, skipped, failed, and incomplete outcomes through the existing notification feed.

User Impact

Enable Claude Code Migration (Experimental) under Kilo's Experimental settings. The migration runs on the next backend start. Claude source files remain unchanged for users who continue using Claude Code, while future global configuration changes are expected in Kilo.
