Problem

Windows test on 2026-03-18 fails with snapshot assertion error:

thread 'config::types::tests::config_default_snapshot' panicked at:
snapshot assertion for 'config_default_snapshot_lsp_policy' failed in line 55

Test: config::types::tests::config_default_snapshot
Platform: Windows (windows-latest in CI)
Severity: HIGH — blocks all subsequent tests (fail-fast)
Reproduction: Run cargo nextest run --config-file .github/nextest.toml config::types::tests::config_default_snapshot on Windows

Root Cause

LSP policy configuration differs on Windows vs macOS/Linux. Either:

1. Default LSP configuration changed and snapshot wasn't updated
2. Snapshot comparison is platform-specific (e.g., path separators, line endings)
3. Windows-specific config behavior not matching snapshot expectations

Investigation Needed

1. Review snapshot file: .snapshots/config_default_snapshot_lsp_policy.snap
2. Compare actual vs expected config in snapshot assertion
3. Check if LSP policy has platform-specific defaults
4. Verify snapshot serialization handles Windows line endings correctly

Might be related to config changes in recent PRs — need to check if SecurityConfig struct lost Copy trait (known issue from workflow patterns).
