* Add GitHub Copilot CLI support
Adds Copilot CLI support through a root plugin manifest, Copilot-specific MCP and hook configuration, and a connect adapter for MCP-only setup.
Includes Windows-safe Copilot MCP command generation, COPILOT_HOME handling, Copilot hook payload normalization, generated hook scripts, and targeted tests for plugin shape, hook execution, and connect behavior.

* Harden Copilot hook handling
Addresses upstream AI review suggestions by aligning the Copilot preToolUse matcher with the hook allowlist, narrowing hook payload fields at runtime, normalizing subagent fallbacks, and tightening hook config validation.

* Support framed stdio MCP transport
Accept Content-Length framed JSON-RPC messages in addition to the existing newline-delimited transport so Copilot CLI can initialize the standalone MCP server.

* Narrow Copilot pre-tool session ids
Ensures pre-tool-use only forwards string session IDs and falls back to unknown for invalid Copilot payload values, with regression coverage for the generated plugin script.
