CodeDebrief v0.17.0

Added

• Added codedebrief clear to remove CodeDebrief config, generated artifacts, installed
  skills, MCP server entries, and managed instruction blocks from the current project
  folder.
• Added codedebrief doctor --errors and codedebrief doctor --errors --clear for
  inspecting or clearing local CLI/MCP diagnostics saved in
  codedebrief-out/codedebrief.errors.jsonl.

Changed

• New codedebrief setup runs keep project config in codedebrief-out/codedebrief.toml
  while preserving compatibility with legacy root codedebrief.toml files.
• Made default setup, update, validate, and doctor output more compact while
  preserving detailed progress behind --verbose and structured output behind --json.
• Expanded default pruning for common cache, build, IDE, and binary output paths before
  analysis starts.
• Auto-scale the default agent_context token budget on large broad requests while still
  honoring explicit token_budget values exactly.
• Reworked the README opening with a clearer project summary, badge row, navigation links,
  and managed-file layout guidance.
