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

# Mixed Technology: 10-node heterogeneous network
#
# Explicit topology with Bluetooth (L2CAP), WiFi, and fiber links.
# Tests that cost-based parent selection produces a tree favoring
# low-cost paths when multiple link technologies coexist.
#
# Topology:
#
# n01 (root)
# / | \
# f f f
# / | \
# n02 n03 n04
# | \ | \ | \
# f BT f f BT f
# | \ | | \ |
# n05 n06 n07 n08 n09
# \ /
# wifi---wifi
# n10
#
# Edges and link types:
# Fiber: n01-n02, n01-n03, n01-n04, n02-n05, n03-n07, n04-n09
# Bluetooth: n02-n06, n04-n08
# WiFi: n03-n06, n08-n10
# Fiber: n03-n08, n06-n10
#
# Test subjects:
# - n06 has fiber (n03) and Bluetooth (n02) parents — should pick n03
# - n08 has fiber (n03) and Bluetooth (n04) parents — should pick n03
#
# Netem mutation shifts fiber-only links between normal and degraded.
