 DONE: The editor honours .editorconfig end-to-end. New source-agnostic EditorSettings model (editor_settings.dart) + composition seam (editor_settings_resolver.dart); .editorconfig demoted to a source (editorconfig.dart, own INI parser + glob matcher, root/nearest-wins precedence, no deps). Registry resolves on open and re-resolves open buffers when a .editorconfig is saved in-app (editor.settings-changed; a save hook, not an fs-watch). Editor: Tab/Shift+Tab indent + max_line_length ruler; save applies end_of_line/trim_trailing_whitespace/insert_final_newline.

Passes reliably in isolation and via the gate''s SERIAL test-core pass (''dart test test/pty'', +571 ok), so it is not a logic bug.
+
+Root cause: these tests spawn a real /bin/sh via NativePty and wait on the reader ISOLATE to deliver bytes. Under heavy CPU contention the reader isolate is starved and the 20s ioTimeout (test/helpers/timeouts.dart) elapses before the shell''s first byte / echo response is delivered. Already hardened once (T-108 swapped wall-clock sleeps for event-driven waits; first-byte Completer + 25ms-poll _waitForBuffer), but the isolate-scheduling assumption still breaks under load.
+
+These tests are tagged ''pty'' and are meant to run in the gate''s serial pass. Fix options: (a) ensure the parallel coverage pass EXCLUDES tag:pty (run pty only in the serial pass) so they never compete for isolate scheduling — verify ci/test.sh / dart_test.yaml tag routing; (b) harden against isolate starvation (e.g. give the reader isolate priority, or assert on delivery via a more robust signal); (c) document that ''flutter test --coverage'' over the whole tree is not a supported invocation (use make test + the gate). Prefer (a).
