jpmschweitzerandClaude Opus 4.7 a6ed22405f fix Claude pane hang: cap tail, parse off-isolate, coalesce notifies
test / unit + widget + golden + a11y (push) Failing after 27s
test / integration_test (xvfb) (push) Has been skipped
test / bundle smoke (xvfb 5s) (push) Has been skipped
test / daemon subprocess + web WASM smoke (push) Has been skipped
test / dart doc (lib API) (push) Failing after 27s
The native Claude pane (T-137) picks the newest transcript JSONL by
mtime — which on a live session is this multi-MB active file. On attach
it read and parsed the whole file synchronously on the UI isolate and
fired notifyListeners per item, freezing the app.

Three fixes: cap the initial read to a recent tail (256KB, injectable
for tests); run JSON parsing in a background isolate via Isolate.run;
coalesce the controller's notifications with a zero-duration Timer so a
burst collapses into one rebuild (a microtask-scheduled notify wouldn't
— stream events deliver one per microtask and the notify interleaves).

jpmschweitzerandClaude 0eee456426 add TranscriptReader: tail + parse Claude transcript JSONL (T-136)

Data layer for native Claude rendering (T-132). Resolves the munged
project dir, picks the newest session .jsonl by mtime (Claude doesn't
expose its session id), tails it append-only via a dart:io byte cursor,
and emits a sealed ConversationItem stream (user / tool-result /
assistant text / thinking / tool-use). Skips bookkeeping record types
and degrades gracefully on an unfamiliar transcript `version`. Pure
dart:io + dart:convert, Flutter-free, zero new deps.

The parser is a pure public parseLine(line) -> List<ConversationItem>
so tests exercise the real code (an injectable projectsBase lets the
streaming tests point the real reader at a temp dir) — no shadow
re-implementation. 31 tests under dart test.
