Added docs for experimental LSP tool

[opencode-agent[bot]]

Findings

• 345f4801e feat: add experimental lsp tool (#5886): New user-facing tool (lsp) gated behind OPENCODE_EXPERIMENTAL_LSP_TOOL (or OPENCODE_EXPERIMENTAL). This was not documented.
• ac4b8d62e feat: add nixd as lsp for nix language (#5929): Already documented via the nixd entry in packages/web/src/content/docs/lsp.mdx (no further doc changes needed).
• Other commits (fix:, ci:, docs:) don’t add new user-facing features needing documentation beyond what’s already present.

Docs Added/Updated

• Documented the experimental lsp tool (what it does, how to enable it, example prompts) in packages/web/src/content/docs/lsp.mdx:52.
• Added the lsp tool to the built-in tools list in packages/web/src/content/docs/tools.mdx:216.
• Added OPENCODE_EXPERIMENTAL_LSP_TOOL to the experimental env var table in packages/web/src/content/docs/cli.mdx:322.

Validation

• Couldn’t run the docs build because bun isn’t available in this environment (bun: command not found). If you want, run bun -C packages/web run build locally to verify rendering.
