Summary

Strengthen FluxTuner's type-checking gate by removing --follow-imports=skip from both local and GitHub Actions mypy checks.

Changes

• Update the Makefile gate to run mypy fluxtuner/.
• Update the GitHub Actions quality job to use the same command.
• Preserve the existing mypy configuration and explicit third-party import overrides.

Motivation

The previous gate allowed nine inherited mypy errors to remain undetected. Those errors were resolved in #278.

This change prevents the same import-skipping configuration from hiding similar errors in future development.

Validation

• Official reinforced make gate: PASS
• Pytest: 1,565 passed, 7 skipped
• Mypy: 0 errors across 106 source files
• Ruff format and lint: PASS
• Python compilation and JavaScript syntax: PASS
• pip-audit: no known vulnerabilities
• Bandit: no issues identified

CI acceptance criteria

All quality jobs must pass on Python 3.11, 3.12 and 3.13, in addition to the existing Brynse contract, dependency audit and packaging jobs.

Scope

Two files changed, with no application code or dependency changes.
