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).

"""Regression test: `hermes dashboard --tui` must not hard-crash.
Older Hermes desktop app shells (<= 0.15.x) spawn the backend as::
hermes dashboard --no-open --tui --host 127.0.0.1 --port <PORT>
The ``--tui`` flag was removed from the ``dashboard`` subcommand in cae6b5486
(embedded chat is always on now). When a user's CLI updates past that commit
but their desktop app binary has not, argparse used to reject the unknown flag
with ``error: unrecognized arguments: --tui`` and ``exit(2)`` — the backend
died before it became ready and the desktop GUI showed only "Hermes couldn't
start" with no actionable cause.
The fix adds a hidden, deprecated, accepted-and-ignored ``--tui`` flag to the
dashboard subparser so an old app shell + new CLI degrades gracefully instead
of bricking. These tests pin that contract.
