test: prune low-value tests suite-wide (wave 1) — 46,820 → 28,106 test functions

Systematic prune per AGENTS.md test policy, one pass over every major
test tree (gateway, hermes_cli, tools, agent, run_agent, plugins, cli,
cron, tui_gateway, honcho/openviking, root-level):

- DELETE: source-reading tests (read_text/getsource on prod files),
  change-detector tests (exact catalog counts, model-name snapshots,
  config version literals), mock-echo tests (assert a mock returns what
  it was told), assertion-free/trivial tests, near-duplicate
  parametrizations (boundaries + one representative kept), async/sync
  twin duplicates, cosmetic within-file variations.
- KEEP (mandatory): security/redaction/approval guards, message-role
  alternation invariants, prompt-caching/deterministic-call-id
  invariants, issue-number regression tests (deduped), E2E tests.
- 6 test files deleted outright (script-style/no-assert or fully
  redundant); conftest.py, fakes/, fixtures/ untouched.
- tests/acp/conftest.py added: autouse fixture stubs the live
  models.dev/GitHub/Copilot/Anthropic inventory fetches that ACP server
  tests performed on every session create — test_server.py 147s → 3.4s,
  and the tests are now genuinely hermetic.
- Sleep-based slowness shrunk where safe (codex_ttfb_watchdog,
  compression_concurrent_fork, etc.); no wall-clock assertion tightened.

Verification: full hermetic suite via scripts/run_tests.sh —
2439 files, 31,130 tests passed, 0 failed, 0 flaky retries, 315s wall
(baseline: 583s wall, 13,564s subprocess CPU).

fix(tui): cgroup-aware V8 heap cap so memory-limited containers stop dying silently (#38541 )

The TUI hardcoded --max-old-space-size=8192. V8 is not cgroup-aware, so in a
Docker/k8s container capped below ~9-10GB the heap grows past the container
limit and the cgroup OOM-killer SIGKILLs the Node parent BEFORE V8's own heap
monitor fires. SIGKILL runs no JS handler, writes no [tui-parent] breadcrumb,
and closes the gateway child's stdin — the user sees only a bare gateway
'stdin EOF'. Complements #38224 (trail-text cap), which reduced pressure but
left the 8GB-vs-container mismatch in place.

- _read_cgroup_memory_limit(): read cgroup v2 (memory.max) then v1
  (memory.limit_in_bytes); handle 'max', the v1 unlimited sentinel, blank/zero,
  and >=1PB as unconstrained.
- _resolve_tui_heap_mb(): unconstrained -> 8192; constrained -> 75% of the
  cgroup limit (headroom for non-heap RSS + the Python child sharing the
  cgroup), floored at 1536MB, never above 8192.
- NODE_OPTIONS block uses the sized value; still respects a user-supplied
  --max-old-space-size.

Net: V8 now GCs/exits gracefully (onCritical breadcrumb fires) instead of being
reaped silently. Display/transport only — no agent context or behavior change.

Tests: tests/hermes_cli/test_tui_heap_sizing.py (20 tests).
