Pull request overview
This PR primarily introduces a comprehensive, book-style documentation set for the VS Code Agent Host subsystem (architecture, protocol/state, storage, changesets, permissions, etc.) under docs/platform/agentHost/, and also tweaks Copilot CLI model discovery to optionally include an auto model entry based on configuration.
Changes:
- Added an extensive Agent Host documentation set with overview, technical deep-dives, reference pages, and update/review playbooks.
- Added many “research / subagent” traceability notes and TODO trackers used during documentation regeneration.
- Updated Copilot CLI language model provider to prepend an
automodel whenCLIAutoModelEnabledis enabled.
