Make namespace filters configurable in ReportCommand

[Copilot]

The ReportCommand contained hardcoded namespace filters specific to a single project (App\Kernel, App\CLI, PhpParser, Monolog, etc.), making it non-reusable without modification.

Changes

• Added --exclude-namespace option (repeatable) to configure namespace exclusions
• Replaced hardcoded project-specific filters with minimal general-purpose defaults (Doctrine, Symfony, Psr)
• User-provided exclusions replace defaults entirely, allowing full control
• Updated README with usage examples

Usage

# Use defaults (Doctrine, Symfony, Psr)
vendor/bin/console tactix:report src/

# Custom exclusions (replaces defaults)
vendor/bin/console tactix:report src/ \
  --exclude-namespace="App\\CLI\\" \
  --exclude-namespace="App\\Infrastructure\\"
