feat(lsp): add LSP tools integration with workspace/configuration support

- Add 7 LSP tools: hover, goto_definition, find_references, document_symbols, workspace_symbols, diagnostics, servers
- Support multiple LSP servers: typescript, gopls, pyrefly, basedpyright, ruff, rust-analyzer, clangd, sourcekit-lsp, ruby-lsp
- Read LSP config from opencode.json with disabled server support
- Handle server requests: workspace/configuration, client/registerCapability, window/workDoneProgress/create
- Send workspace/didChangeConfiguration after initialized for basedpyright compatibility
- Uint8Array-based buffer for reliable LSP message parsing
