Subject: [PATCH 1/6] fix(@angular-devkit/schematics-cli): correctly parse
 inline boolean values in CLI options

When CLI options defined as boolean are provided with inline values like '--debug=false' or '--dry-run=false', 'node:util.parseArgs' in non-strict mode returns string values ('false' / 'true') rather than booleans. This caused false values to be treated as truthy.

Normalize string boolean values in CLI options.

Closes #34199
