[patrol_cli] Upgrade package_config

[PiotrRogulski]

To resolve the dependency conflicts, I also had to remove build_runner from dev deps (it wasn't used anyway) and upgrade leancode_lint to use the new analyzer.

Code Review

This pull request updates the minimum Dart SDK constraint to >=3.9.0 <4.0.0, upgrades several dependencies (including package_config and leancode_lint), and removes build_runner and custom_lint from dev_dependencies. It also removes the custom_lint plugin from analysis_options.yaml. The review feedback highlights that removing custom_lint from both the analysis options and dependencies will completely disable the custom lint rules from leancode_lint, as analyzer plugins are not transitively inherited. It is recommended to retain and upgrade custom_lint to a compatible version instead of removing it.

packages/patrol_cli/analysis_options.yaml (3-5)

In Dart, analyzer plugins (such as custom_lint) are not transitively inherited from included analysis options files (like package:leancode_lint/analysis_options.yaml). Removing the custom_lint plugin from this file will completely disable all custom lint rules provided by leancode_lint. If you want to keep using the custom lints from leancode_lint, you must retain the custom_lint plugin in analysis_options.yaml and keep custom_lint in your dev_dependencies.

packages/patrol_cli/pubspec.yaml (44)

Removing custom_lint from dev_dependencies will prevent the custom_lint analyzer plugin from being resolved and executed, disabling all custom rules from leancode_lint. If the removal was due to dependency conflicts with custom_lint: ^0.8.1, consider upgrading custom_lint to a newer version compatible with Dart 3.9.0 and leancode_lint: ^24.0.0 instead of removing it entirely.
