fix(test): add Docker skip guards + stabilize flaky tests under load

[tamirdresher]

What

Add Docker availability skip guards and timeout adjustments to fix flaky tests under full-suite load.

Why

Issue #582 reports ~24 intermittent test failures in two categories:

1. Docker-dependent tests (~15) fail when Docker Desktop isn't running
2. Timing/resource contention tests (~9) fail under parallel load but pass in isolation

This affects CI reliability for everyone — false negatives on PRs waste reviewer time.

Proposed Fix

1. Add describe.skipIf(!dockerAvailable) guard to Docker-dependent test files
2. Increase timeout margins for speed-gate tests
3. Add retry logic for ENOTEMPTY cleanup errors

🔄 Ralph status: PR #679 addresses this (also covers #582, now closed as duplicate). Needs rebase (behind dev). Small fix — 3 files, Docker skip guard + timeout.
