Johnathan Corgan 965de26239 testing: make ci-local.sh preemption-safe with per-run docker isolation
A CI worker may preempt an in-flight ci-local.sh run (SIGTERM, then SIGKILL
after a grace period) to restart on a newer commit. For that kill to be safe,
the script must clean up after itself and never let a dying run collide with
its restart. It previously had no signal handling, shared the default compose
project name across runs, and tore down each suite only at the suite end.

- Derive a per-run id (honoring FIPS_CI_RUN_ID, else short-sha+random) and
  namespace every docker resource to it: a fipsci_<run>_<suite> compose project
  per suite and per parallel chaos child, and per-run image tags
  (fips-test:<run>, fips-test-app:<run>) retagged to :latest only after both
  builds succeed so :latest never points at a half-built image.
- Install a bounded, idempotent teardown trap on SIGTERM/SIGINT (+ EXIT): reap
  parallel chaos children, then force-remove this run's docker resources via
  the new ci-cleanup.sh, wrapped in timeout so a stuck down cannot wedge it.
- Exit 143 (SIGTERM) / 130 (SIGINT), distinct from 0 (pass) / 1 (failed), so a
  preempting worker tells a cancelled run from a real failure.
- Add ci-cleanup.sh (also ci-local.sh --reap): force-removes leftover CI
  resources by the com.corganlabs.fips-ci=1 label and the fipsci_ project
  prefix, robust to however a prior run died.
- Label every per-suite docker resource so the label sweep reaps it after a
  SIGKILL regardless of network name: direct docker run/network resources, the
  sidecar compose services, and every per-suite compose network (acl-allowlist,
  boringtun, firewall, nat, static, both tor suites, and the chaos generator
  template). Parametrize the static/sidecar compose image refs so the per-run
  tags are honored.
- Give each parallel chaos child a unique /24 from 10.30.x (a new --subnet
  override on the sim CLI, assigned per-child in ci-local.sh) so parallel
  children never collide on a shared docker subnet, and a chaos net can never
  span a fixed-subnet suite (sidecar/static in 172.20.x). 10.30.x sits outside
  docker's default-address-pool range, so an auto-assigned net cannot land on
  it either; node IPs derive from the subnet, so no scenario config changes.

Johnathan Corgan 9e63b42bd9 Consolidate Docker test harness infrastructure
Replace 4 near-identical per-harness Docker setups with unified shared
infrastructure. Net result: -463 lines across 55 files, faster CI
(8.5 min vs ~13.5 min), 14 scenarios (down from 21).

Unified Docker image (testing/docker/):
- Single Dockerfile (trixie-slim) with FIPS_TEST_MODE env var for
  mode dispatch: default, chaos, sidecar, tor-socks5, tor-directory
- Single entrypoint.sh with conditional logic per mode
- Replaces 5 Dockerfiles, 3 entrypoints, 4 resolv.conf copies

Shared build and libraries (testing/scripts/, testing/lib/):
- testing/scripts/build.sh: single build script with macOS zigbuild
  support, replaces 4 per-harness copies
- testing/lib/derive_keys.py: shared key derivation module, replaces
  3 copies of derive-keys.py
- testing/lib/log_analysis.py: shared log analysis extracted from
  chaos sim/logs.py, with CLI interface and rekey cutover tracking
- testing/lib/wait-converge.sh: shared convergence wait helpers
  (wait_for_links, wait_for_peers) using fipsctl JSON polling

Scenario consolidation:
- Remove 7 redundant scenarios: tcp-chain (subsumed by tcp-mesh),
  tcp-only (subsumed by tcp-mesh), chaos-10 (replaced by
  churn-mixed --nodes 10), churn-10/churn-20/churn-20-mixed
  (subsumed by parameterized churn-mixed), cost-mixed-7node
  (overlaps mixed-technology)
- Add churn-mixed scenario with --nodes flag for scale testing
- Reduce idle scenario durations: smoke-10 60s→30s,
  ethernet-only 90s→30s, cost-avoidance 120s→45s,
  depth-vs-cost 120s→45s, bottleneck-parent 120s→60s,
  mixed-technology 180s→90s

CI updates:
- ci-local.sh: unified image build, structured chaos suite entries
  with per-scenario flags, --skip-build for sidecar
- ci.yml: shared binary install + image build step, updated scenario
  matrix, chaos_flags support for parameterized scenarios
- Add tcp-mesh and congestion-stress to CI matrix
- Static ping test uses active peer convergence detection instead
  of hardcoded 5s sleep

Chaos infrastructure improvements (from discovery-rework branch):
- Pre-built Docker image instead of per-service build at scale
- --nodes flag in chaos.sh for runtime topology size override

Johnathan Corgan 66c268a564 Add static and stochastic Docker test harnesses
Move examples/docker-network/ to testing/static/ and add testing/chaos/
as a new stochastic simulation harness.

testing/static/ — Static 5-node test harness:
- Fixed mesh, chain, and mesh-public topologies with docker compose
- Manual test scripts (ping, iperf, netem)
- Build script, config generation, key derivation

testing/chaos/ — Stochastic network simulation:
- Python orchestrator generating N-node FIPS meshes with dynamic
  network conditions, driven by reproducible YAML scenarios
- Topology generation: random geometric, Erdos-Renyi, or chain
  graphs with BFS connectivity guarantee
- Per-link netem: HTB classful qdiscs with u32 filters for per-peer
  impairment (delay, loss, jitter), stochastic mutation across
  configurable policy profiles
- Per-link bandwidth pacing: HTB rate limiting with configurable
  tiers (1/10/100/1000 mbps) randomly assigned per edge
- Link flaps: tc netem 100% loss with graph connectivity protection
- Node churn: docker stop/start with netem re-application on restart,
  shared down_nodes tracking across all managers
- Traffic generation: random iperf3 sessions between node pairs
- Down-node guards: all docker exec callers check container liveness,
  auto-detect crashed containers via is_container_running() safety net
- Log collection and post-run analysis (panics, errors, sessions,
  MMP metrics, tree reconvergence)
- chaos.sh wrapper with --seed, --duration, --verbose, --list options
- Four scenarios: smoke-10, chaos-10, churn-10, churn-20
