feat(lsp): add 20 additional LSP servers from OpenCode reference

Add comprehensive LSP server support covering web frameworks, linters,
and system languages:

Phase 1 - Web/Common:
- Biome: JS/TS/JSON/CSS linter with auto-download
- Svelte: Svelte language support with auto-download
- Astro: Astro language support with auto-download
- YamlLS: YAML language server via npm
- BashLS: Shell script support via npm
- DockerfileLS: Dockerfile support via npm

Phase 2 - Additional Languages:
- Rubocop: Ruby linter (requires gem install)
- ElixirLS: Elixir language server with Mix build
- ZLS: Zig language server with GitHub auto-download
- C#/F#: .NET language support via dotnet tool
- SourceKit: Swift (macOS system-only)
- Clangd: C/C++ with GitHub auto-download
- JDTLS: Java via Eclipse download
- LuaLS: Lua with GitHub auto-download
- PHP: Intelephense via npm
- OCaml: OCaml-LSP (system-only)
- TerraformLS: HashiCorp Terraform with GitHub auto-download
- TexLab: LaTeX with GitHub auto-download
- Gleam: Gleam language (system-only)

All servers follow existing patterns with proper:
- Exit code validation for archive extraction
- Cross-platform fs.readdir() instead of shell commands
- Mix build step error handling for ElixirLS
- Version tracking with marker files

Closes #50
