Johnathan Corgan 49163befd5 Give each local CI run its own docker build context
Scoping the image tag was never sufficient on its own. Every build read one
unscoped directory in the working tree, into which each run copies the
binaries it just built, so two concurrent runs raced on the contents of the
context as well as on the name of the result — and a run could produce a
correctly-per-run-tagged image built from the other run's binaries.

The run now copies the context's tracked files into its own directory,
installs its binaries there, and builds from it, exporting the path so every
other consumer follows. Deliberately not carried over: a previous run's
binaries, since inheriting them is the failure this prevents. The path is
absolute because compose resolves a relative build context against the
compose file's own directory rather than the working directory, which was
measured rather than assumed.

The chaos entry script gated the whole simulation on a binary in the shared
directory by literal path, so it moves in this same commit: left behind, it
would have failed on a clean checkout and, worse on a host with leftovers,
passed while reading a binary that was not the one under test.

Teardown removes the directory on red runs as well as green, since it holds
only reproducible content and is never the evidence of a failure. The
worker's SIGKILL runs no trap, so the cleanup script also sweeps contexts
left by a preempted run, and the ignore rule keeps a concurrent run from
showing up as untracked working-tree noise.

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
