`lib/kernel/src/toolchain.dart` is a `ChangeNotifier`, so it pulls in
`package:flutter/foundation.dart`. `GitClient` and `PqlClient` imported
it for the resolved binary paths, which leaked Flutter through the
`package:clide/clide.dart` barrel — breaking `dart test` on every core
subsystem suite (`ci/test_core.sh`), since pure Dart can't compile
Flutter packages.
Split the Flutter-free pieces into `toolchain_paths.dart`: `ResolvedPaths`,
`resolveToolchainPaths`, and a new read-only `ToolchainView` interface
with a `ToolchainView.resolved()` const factory. `Toolchain` now
implements `ToolchainView`; the clients depend on the interface. Core
test setups that built a `Toolchain` just to call `applyResolved`
switch to the factory.

Two fault-injection test files driving every pql.* and git.* daemon
handler with a Client whose toolchain points at a non-existent
binary. Each underlying Process.run throws ProcessException → wrapped
as PqlException / GitException → the handler's catch branch fires
and surfaces a toolError IpcResponse.
- pql_commands_errors_test (18 cases): every pql.* command lands in
the catch + _pqlError helper.
- git_commands_errors_test (14 cases): every git.* command lands in
the catch + _gitError helper. Skipped: stage-hunk + unstage-hunk
which go through GitClient._applyPatch (uses Process.start, throws
ProcessException directly without rewrapping in GitException).
Coverage: src/daemon/pql_commands.dart 105/149 -> 148/149 (99%);
src/daemon/git_commands.dart 122/146 -> 142/146 (97%).
Total coverage 91.59% -> 92.33%; floor bumped to 92.
