* refactor(lsp): migrate to vscode-jsonrpc for improved stability
Replace custom JSON-RPC implementation with vscode-jsonrpc library.
Use MessageConnection with StreamMessageReader/Writer.
Implement Bun↔Node stream bridges for compatibility.
Preserve all existing functionality (warmup, cleanup, capabilities).
Net reduction of ~60 lines while improving protocol handling.

* fix(lsp): cleanup orphaned LSP servers on session.deleted
When parallel background agent tasks complete, their LSP servers (for
repos cloned to /tmp/) remain running until a 5-minute idle timeout.
This causes memory accumulation with heavy parallel Sisyphus usage,
potentially leading to OOM crashes.
This change adds cleanupTempDirectoryClients() to LSPServerManager
(matching the pattern used by SkillMcpManager.disconnectSession())
and calls it on session.deleted events.
The cleanup targets idle LSP clients (refCount=0) for temporary
directories (/tmp/, /var/folders/) where agent tasks clone repos.
* chore: retrigger CI checks
Previously, when an LSP server was configured but not installed, the error
message said "No LSP server configured" which was misleading. Now the
error message distinguishes between:
1. Server not configured at all
2. Server configured but not installed (with installation hints)
The new error messages include:
- Clear indication of whether server is configured vs installed
- Installation commands for each built-in server
- Supported file extensions
- Configuration examples for custom servers

Implement cross-platform process cleanup handlers for LSP servers.
Added registerProcessCleanup() method to LSPServerManager that:
- Kills all spawned LSP server processes on process.exit
- Handles SIGINT (Ctrl+C) - all platforms
- Handles SIGTERM (kill signal) - Unix/macOS/Linux
- Handles SIGBREAK (Ctrl+Break) - Windows specific
This prevents LSP servers from becoming orphan processes when opencode terminates unexpectedly.
