The merged UI/platform thread on macOS (Flutter 3.41) freezes on any
synchronous work — file I/O, Process.run, even isolate spawning during
early frames. No timing workaround (Timer, addPostFrameCallback,
Future.delayed) was reliable.
Fix: spawn a backend isolate that owns the DaemonDispatcher, GitClient,
PqlClient, FilesService, EditorRegistry, and Toolchain resolution. The
main isolate stays free for rendering. Communication uses SendPort with
the existing IPC message protocol (IpcRequest/IpcResponse/IpcEvent) —
zero new serialization.
New files:
backend.dart — spawns isolate, manages SendPort/ReceivePort
backend_entry.dart — isolate entry point, boots all services
isolate_client.dart — replaces InProcessClient for production
Toolchain now exposes resolveToolchainPaths() as a top-level function
with self-contained PATH expansion (no module-level state that would
prevent isolate message passing).
ClideTestApp gains boot-sequence tests: compute(), Isolate.run(),
sequential Process.run, and the full resolve+exec chain.

Six improvements to the testmode harness:
1. Shell passthrough tests use the resolved shell instead of
hardcoded /bin/zsh.
2. Exit code reflects test results (non-zero on any failure).
3. JSON summary line for machine-readable parsing.
4. IPC round-trip smoke (ping, version, unknown-cmd, encode/decode).
5. Extension lifecycle smoke (register + activate files, diff,
git, terminal; theme loading for all four bundled themes).
6. Test categories via CLIDE_TESTMODE dart-define (toolchain, ipc,
extensions, all). Makefile exposes TESTMODE_CATEGORY variable.
Also switches main.dart from bool.fromEnvironment to
String.fromEnvironment so category values other than "true" work.

Toolchain centralizes binary resolution — replaces five ad-hoc
mechanisms (expandedPath, _resolveGit, _resolve, _resolvePtyc,
_existsOnPath). Resolves via Future.delayed after runApp to avoid
blocking the merged UI/platform thread on macOS.
GitClient wraps all git operations with a typed API. Every subprocess
call goes through _run() using toolchain.git + toolchain.gitEnv.
Replaces free functions in operations.dart.
Native directory picker: NSOpenPanel on macOS (method channel in
AppDelegate), GtkFileChooserDialog on Linux. Falls back to text-input
dialog on web or MissingPluginException. Shows "No git repo found"
dialog when the selected directory is not a git repository.
PqlClient and pane commands updated to use Toolchain. ToolCheck
replaced by Toolchain.missing/allOk. All IPC handlers now catch
GitException to prevent unhandled exceptions on the merged thread.

Extension listens to its own selection channel and activates the
detail tab in the context panel — fixes the chicken-and-egg where
the controller only subscribes after the widget builds. Registration
order in main.dart now determines sidebar icon rail order: tickets
first, then decisions, files, git, pql, problems.

DaemonBus (was EventBus): typed events for system/IPC layer.
MessageBus: channel-based pub/sub for UI/extension coordination.
Messages carry publisher (auto-stamped from extension ID),
channel (required), timestamp, and payload. Subscribe by
publisher, channel, or both — zero collision across extensions.
Extension context gains publish() and subscribe() convenience
methods that auto-stamp the extension's ID as publisher.

ToolCheck kernel service checks ptyc/pql/tmux/git availability
once at boot, shared by status bar and welcome screen. Welcome
status line shows "application ok" in green or lists missing
tools in amber. Logo doubled to 144px. DialogHost moved inside
Expanded to fix blank workspace. Welcome maxWidth 850px, path
overflow fixed with Flexible.

Prebuilt ptyc binary sits alongside libtree-sitter.so in the
platform-specific native directory. Resolution order:
native/linux-x64/ptyc → ptyc/bin/ptyc → ~/.local/bin/ptyc → PATH.
Eliminates the make ptyc-build step on fresh clones.

The Flutter app now looks for ptyc/bin/ptyc relative to the
workspace root before falling back to PATH. Fixes
"ProcessException: No such file or directory. Command: ptyc"
when running in-process without ptyc installed globally.

InProcessClient dispatches IPC requests directly to handlers in the
same process, bypassing the unix socket entirely. All subsystem
registries (pane, files, editor, git, pql) are created in the
Flutter app's boot sequence and registered on a DaemonDispatcher.
Events bridge to the kernel EventBus via _BusEventSink. The app
no longer needs `clide --daemon` running.

Single Flutter package at the repo root. All code, tests, assets,
and platform directories moved from app/ to root. Package renamed
from clide_app to clide — all imports rewritten. Merged pubspec
combines core (ffi) and app (flutter, yaml, xterm) dependencies.
Makefile simplified: no APP_PRESENT conditionals, no cd, no daemon
lifecycle. 317 tests pass.
