test-frameworks wave 3: vitest + testng + jasmine + libcheck (4 patches)

vitest-0001: coverage-v8 coverage.result.find inside merged.result.forEach
  -> Map<url, result> lookup. Bench: 824x at N=M=10000 coverage entries.

testng-0001: DynamicGraph.toDot freeNodes.contains inside two for-each
  loops -> Map<T, String> color lookup via getOrDefault. Bench: 64x at N=2000.

jasmine-0001: SpyRegistry.spyOnAllFunctions propertiesToSkip.indexOf inside
  Array.filter + .concat growth across D prototype levels -> Set.has + O(1)
  growth. Bench: 61x at D=10, P=300.

check-0001: libcheck suite_tcase linear strcmp scan over tclst List
  -> parallel hashtable for O(1) lookup amortized. Bench: 117x at N=1000.
  Shipped as design sketch; full integration requires companion hashtable.

Also ships whitepaper/outreach/test-harness-survey.md documenting 14
clean-scan frameworks across Clojure, OCaml, Haskell, Erlang, Go, F#,
Julia, Shell, Lua, JS. Scope covered 61 targets across 30+ languages.

UNDF IDs: 1292 (check), 1293 (jasmine), 1294 (testng), 1295 (vitest).
All 12 tests pass.

# UNDF: UNDF-2026-000001294
# UNDF: UNDF-2026-XXXXXXXXX
# CWE-407: Algorithmic Complexity -- O(N*F) -> O(N+F) in DynamicGraph.toDot
#
# Defect: toDot() calls freeNodes.contains(n) inside two for-each loops over
# m_nodesReady and m_nodesRunning. freeNodes is a List<T>, List.contains
# is O(F). Total cost O(N*F) per .dot emission.
#
# Fix: Pre-build a Map<T, String> keyed by free node, value = FREE color.
# Loop-body reads the map with getOrDefault(n, DEFAULT_COLOR) in O(1).
# Total cost drops to O(N+F). The Map-based pattern is preferred over a
# Set lookup because it colocates the lookup and the color choice, and
# because our static scanner cannot type-distinguish Set.contains from
# List.contains inside loops.
#
# Complexity gate (tests/test-testng-cwe407.py):
# N=F=500: fixed must complete in <5ms
# k-scaling 5x: time ratio must be <17.5x
