Two new test files:
- fix_dialog_test.dart — surface tests for the controller API
the new Fix dialog reads: fixesFor() returns the analyzer-
attached list, analyzerErrorCount tracks errors, and the
English AnalyzerStrings produce the labels the dialog
renders ('Install <cap>', 'Add source for <cap>…', etc).
- inline_approval_test.dart — covers the FlowRunDriver
approval hooks added in 0.21.0. Validates the default
stubs throw UnsupportedError (so legacy hosts surface in
CI rather than at runtime) and that a fake driver
implementation can drive the happy + reject paths.
44 editor tests green.
