Godot Agent Loop 2.0.0

Godot Agent Loop 2.0.0

Godot Agent Loop 2.0.0 is the lean feedback loop: author files, validate,
run, observe, interact, assert. The tool surface drops from 173 tools to 64 —
109 tools are removed and the advertised core is a reviewed 20-tool surface.

BREAKING: lean tool-surface reduction

• The catalog shrinks from 173 to 64 tools; 109 are removed: 70 subsystem
  runtime wrappers (UI, audio, physics, terrain, GI, animation, networking,
  and similar), 38 project file/authoring/settings/CI tools, and the
  deprecated godot_tools alias.
• The advertised core surface is now 20 tools, grouped by role:
  catalog/call (godot_catalog, godot_call), lifecycle (run_project,
  stop_project, get_debug_output, get_project_info, get_godot_version),
  observation (game_screenshot, game_get_scene_tree, game_get_ui,
  game_get_node_info, game_get_errors, game_get_logs), interaction and
  verification (game_scenario, game_wait_until, validate_scripts,
  run_project_tests, verify_project), and editor session/transaction
  (editor_session, editor_transaction).
• The remaining 44 tools stay available as hidden tools reachable through
  godot_catalog + godot_call: input primitives, privileged generics, node
  generics, and ship tooling.
• GODOT_MCP_AUTHORING_MODE and benchmark:loop are removed. Clients that
  still call godot_tools receive an unknown-tool error and must switch to
  godot_catalog/godot_call.

Migration

• Author .gd/.tscn/.tres/project.godot with the coding agent's own
  file tools; use editor_transaction in watched mode for editor-native edits.
• Reach the 44 hidden tools via godot_catalog + godot_call.
• Opted-in agents use the privileged reflection/code-execution generics in
  place of the deleted subsystem runtime wrappers.
• The previously prepared but never tagged 1.2.0 work (editor-bridge routing
  of project.godot mutations) ships in this release; the settings-tools routing
  described in the 1.2.0 notes was removed by the reduction.

Verification

51 unit tests and 23 e2e tests pass on Godot 4.7. Protocol conformance is 5/5
for the 20 advertised tools. The core surface is 32,787 bytes / ~8,197
estimated tokens, a 92.39% reduction against the full 64-tool surface.
