<issue_title>[Code Quality] Investigate sentrux "0 rules checked" tooling gap despite .sentrux/rules.toml defining 4 rules</issue_title>
<issue_description>## Description

The Daily Sentrux Report - 2026-08-04 flagged that the sentrux quality-gate check logged "0 rules checked" in its run despite .sentrux/rules.toml defining 4 rules (including a god-file ceiling of 1). This is a possible tooling/wiring gap: the god-file count is currently 3 (up from 2), which should have breached the configured ceiling rule and produced a violation, but no rule violations were reported at all.

Suggested Changes

• Investigate why the sentrux check step reports 0 rules checked when .sentrux/rules.toml defines 4 rules (path/config wiring, tool invocation flags, or version mismatch)
• Confirm the god-file ceiling rule (max 1) is actually being evaluated against the current count of 3
• Fix the invocation/config so rule violations are correctly detected and surfaced in future sentrux runs

Files Affected

• .sentrux/rules.toml
• Sentrux invocation step in the daily sentrux workflow (.github/workflows/*sentrux*.md or equivalent CI/analysis script)

Success Criteria

• Sentrux run logs report the correct rule count (4) as checked
• The god-file ceiling breach (3 > 1) is correctly flagged as a rule violation in the next run
• No regression to existing sentrux report generation

Priority

Medium - a silent tooling gap means quality-gate violations (like the god-file ceiling) go undetected.
