refactor(lsp): clean up lsp_servers references and update prompts to use PascalCase

- Remove dead lsp_servers function from tools.ts
- Update utils.ts to reference LspServers (OpenCode built-in)
- Update AGENTS.md: 7 tools → 3 tools
- Update init-deep.ts prompts to use PascalCase OpenCode tools
- Update refactor.ts prompts to use PascalCase OpenCode tools
