Essential workflow fixes:
- ci.yml: add SQLX_OFFLINE=true, replace fictitious cargo subcommands
(test-unit, ci-lint, audit-deps, etc.) with real cargo commands,
remove broken 9-way test matrix, remove instrument-coverage RUSTFLAGS
- test.yml: add SQLX_OFFLINE=true to build-check job, fix conflicting
clippy flags (-D and -W on clippy::all), update JWT secret to 32+ chars
- compilation-guard.yml: add SQLX_OFFLINE=true, remove references to
non-existent paths (services/trading-engine, crates/common/types),
remove dangerous auto-commit-to-main, remove MIRI on missing packages
Deleted duplicates (justification):
- comprehensive_testing.yml: duplicate of comprehensive-testing.yml
(same purpose, underscore vs hyphen naming)
- production-deploy.yml: duplicate of production-deployment.yml
(both named "Production Deployment Pipeline", this one has stale paths)
- coverage-fixed.yml: duplicate of coverage.yml
(uses deprecated actions-rs/toolchain@v1 and actions/cache@v3)
- performance.yml: duplicate of benchmark_regression.yml
(both "Performance Regression Detection", this one less mature)
- quality-baseline.json: not a workflow, stale fake data (999 warnings)
- quality-metrics.json: not a workflow, stale fake data
