feat!: remove --fix from audit/lint/test — refactor owns all code changes

[chubes4]

Summary

Resolves #864. The --fix flags on audit, lint, and test were duplicate entry points into the same refactor engine. This removes them, making refactor the single source of truth for all code changes.

Mental model

audit, lint, test  →  find problems (read-only)
refactor           →  fix problems (writes)

What was removed

CLI flags:

• audit: --fix, --write, --max-iterations, --warning-weight, --info-weight, --no-lint-smoke, --no-test-smoke, --preview
• lint: --fix
• test: --fix (including test --drift --fix)

Code (-450 lines):

• AuditCommandOutput::Fix variant
• run_fix_workflow() from code_audit/run.rs
• plan_autofix() from lint/run.rs
• Autofix planning block from test/run.rs
• process_ratchet() (dead after removing run_fix_workflow)

What's unchanged

The underlying refactor engine is untouched:

• run_audit_refactor(), run_lint_refactor(), run_test_refactor()
• build_refactor_plan() with --from audit/lint/test/all
• FixResult, fix policy, chunked application, sandbox isolation, verification gates
• refactor rename, transform, decompose, move, propagate

Migration

# Before
homeboy audit my-component --fix --write
homeboy lint my-component --fix
homeboy test my-component --fix

# After
homeboy refactor my-component --from audit --write
homeboy refactor my-component --from lint --write
homeboy refactor my-component --from test --write
homeboy refactor my-component --from all --write  # all sources in one pass

The CI action (homeboy-action) already defaults to refactor --from all --write as of v2 (PR #102).

Verification

• cargo check — clean compile, zero warnings
• cargo test — all 25 tests pass
• Rewritten audit test validates read-only mode
