When the active toolchain's swift-format is incompatible with the .swift-format config schema (e.g. Swift 6.1 CI vs 6.2+ config), the plugins now emit a detailed warning and skip linting/formatting instead of failing the build. Real lint violations still fail as before. Build tool plugin: preflight probe runs swift-format against a trivial file before returning the prebuild command. If the config is unparseable, returns [] with a warning diagnostic. Command plugin: config-related failures downgraded from Diagnostics.error to Diagnostics.warning with actionable context. bin/lint: captures stderr, detects config errors, exits 0 with warning.
