feat: complete git-seo integration (100%)

Wired up GitSeoAnalyzer into glambot audit pipeline with configuration
options for enable/disable and auto-apply behavior.

Changes:
- src/config/mod.rs: Added git-seo config options to SeoConfig
  - enable_git_seo: Option<bool> (default: true)
  - enable_auto_apply: Option<bool> (default: false for safety)

- src/main.rs: Integrated GitSeoAnalyzer into handle_audit()
  - Runs as fifth analyzer after machine analyzer
  - Respects config.seo.enable_git_seo flag
  - Gracefully handles git-seo unavailability (doesn't fail audit)
  - Results populated in AuditResult.git_seo field

Configuration example:
```yaml
seo:
  enable_git_seo: true
  enable_auto_apply: false  # Manual approval required
```

Integration flow:
1. glambot audit runs all 5 analyzers (visual, accessibility, seo, machine, git-seo)
2. git-seo analyzer shells out to git-seo CLI
3. Parses JSON report, converts to glambot findings
4. Findings included in overall error/warning counts
5. Can block release if SEO score critically low

Requirements:
- git-seo CLI installed (https://github.com/hyperpolymath/git-seo)
- Git remote configured (origin)
- GITHUB_TOKEN for API analysis (optional but recommended)

Status: Glambot ↔ Git-SEO integration COMPLETE (100%)
