adbad508 - refactor: Migrate command summaries and delete legacy task paths (#13536)

refactor: Migrate command summaries and delete legacy task paths (#13536) ## Intent Final Phase 4 gate: dry-run/run summaries must use the same catalog display facts as execution, and production code must no longer call `Toolchain` task-command callbacks. Those callbacks and their JavaScript/Cargo adapters are deleted. **Stack:** Phase 4 layer 9. Base = `shew/turbo-5823-migrate-native-task-query-devtools-and-lsp-views`. ## Changes - Summary `command` text uses catalog `display` - Engine implicit registration uses catalog `registered` - Task-access Next.js detection uses observation vocabulary - Delete `Toolchain::{task_command,task_display_command,authors_task,registered_tasks,registers_task,defines_task}` and JS/Cargo impls - `ARCHITECTURE.md` marks Phase 4 complete ## Out of scope `task_defaults` / derived I/O / cache contracts (TURBO-5789), total `PackageInfo` deletion. ## Testing - `cargo test -p turborepo-engine --lib` (127 passed) - `cargo test -p turborepo-run-summary --lib` (43 passed) - `cargo test -p turborepo-repository --lib test_javascript_task_command` - `cargo test -p turborepo-repository --lib test_cargo_task_commands` - `cargo clippy … -- -D warnings` Closes TURBO-5824. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Anthony Shew <anthonyshew@users.noreply.github.com>
