feat: implement Phase 1 testing infrastructure improvements

This commit implements critical security and quality improvements to the
Hera testing infrastructure as part of a comprehensive 8-week remediation
plan. All changes are evidence-based and follow industry best practices.

Changes include:

CI/CD Security Hardening:
- Fix security gates in test.yml (fail_ci_if_error: true)
- Remove continue-on-error from npm audit in security.yml
- Pin all GitHub Actions to commit SHAs for supply chain security
  * actions/checkout@v4.3.0
  * actions/setup-node@v4.4.0
  * actions/upload-artifact@v4.6.2
  * codecov/codecov-action@v4.6.0
  * github/codeql-action@v3.31.2

Coverage Threshold Updates:
- Update vitest.config.js with gradual threshold increases
- Phase 1: 10% overall, 70% for tested auth modules (prevent regression)
- Target (Week 8): 70% overall, 85% security modules
- Thresholds will increase as new tests are added per ACTION_PLAN.md

Pre-Commit Hooks:
- Install and configure husky + lint-staged
- Add pre-commit hook for automated linting and testing
- Configure lint-staged to run eslint --fix and vitest on staged files
- Ensure coverage doesn't decrease on commits

Comprehensive Documentation:
- ADVERSARIAL_ANALYSIS.md: Security-focused analysis of testing gaps
- SHIFT_LEFT_STRATEGY.md: Systematic prevention strategy
- EOS_CLI_IMPROVEMENTS.md: Design for eos CLI automation tool
- ACTION_PLAN.md: 8-week remediation roadmap with specific tasks

This addresses critical gaps identified in the testing infrastructure:
- Only 2.3% code coverage (vs. 80-90% industry standard)
- 11 critical security modules untested
- 85+ uncovered error scenarios
- Disabled CI/CD security gates
- No pre-commit automation
