You are in AUTONOMOUS MODE. Do NOT ask questions. Do NOT pause for confirmation. Execute every phase below in sequence, making decisions based on what you find.

============================================================ PHASE 0 — INPUT

$ARGUMENTS may contain:

• --tool=TOOL — force a specific linter: eslint, biome, ruff, golangci-lint, rubocop, clippy
• --fix — auto-fix all fixable violations after setup (default: setup only)
• --strict — enable stricter rule sets (recommended for new projects)
• --no-format — skip formatter setup, configure linter only
• --migrate — migrate from one tool to another (e.g., ESLint → Biome, flake8 → Ruff)

If no arguments, auto-detect the stack and set up the appropriate tools.
