teknium1 d10bb2ab6f test: make tests/ mirror the source tree; drop issue numbers from filenames
`scripts/run_tests.sh tests/<dir>/` is how a change gets its regression
coverage run, so a test filed under the wrong directory is a test nobody
runs when that code changes. Two kinds of drift had accumulated.

Parallel directories for one source package, folded into the mirror:
  tests/acp        -> tests/acp_adapter   (its __init__/conftest move with it)
  tests/cli        -> tests/hermes_cli    (prompt_toolkit fixture merged into
                                           hermes_cli/conftest.py)
  tests/run_agent  -> tests/agent         (backoff fixture becomes
                                           agent/conftest.py)
  tests/relay      -> tests/gateway/relay
  tests/state      -> tests/hermes_state

246 loose files at tests/ root, routed by the package they import/patch:
hermes_cli, hermes_state, agent, gateway, tools, plugins, tui_gateway, cron.
Installer and desktop-update script tests go to tests/scripts/{install,
desktop_update}/. 43 tests of root-level modules (batch_runner, utils,
hermes_constants, packaging) stay at the root.

Filenames drop their issue numbers (95 files: test_89315_x.py -> test_x.py);
the number stays in the module docstring where it has context.

Collisions: test_cli_skin_integration.py existed in both tests/ and tests/cli
with different subsets — merged into one (10 tests, all kept);
run_agent/test_pre_compress_memory_context.py -> agent/..._handoff.py;
tests/test_account_usage.py -> agent/test_account_usage_fetch.py;
tests/test_web_server.py -> hermes_cli/test_web_server_ws_ping.py.
Deleted: test_minisweagent_path.py (empty since PR #2804),
test_model_picker_scroll.py (tested a private copy of the logic, imported
nothing), test_process_loop_event_loop_warning.py (asserted asyncio behaviour,
imported nothing from Hermes).

Repo-root path arithmetic (Path(__file__).parents[N], dirname chains) is
bumped for the 202 files that changed depth and verified by evaluating every
such expression against the new location. classify_changes' desktop-updater
lane prefix, tests-os.yml's ignore glob and every in-tree path comment follow
the moves. tests/test_tests_tree_layout.py keeps the tree from drifting back.

"""Regression: the Windows installer must not spawn a bare ``powershell``.
A user on Windows reported the installer getting stuck; running
``irm https://hermes-agent.nousresearch.com/install.ps1 | iex`` failed at the
uv step with::
[X] Failed to install uv: The term 'powershell' is not recognized as the
name of a cmdlet, function, script file, or operable program.
Root cause: ``Install-Uv`` spawned the astral uv installer via a hardcoded
bare ``powershell`` command. That name resolves only to *Windows PowerShell*
and only when its System32 directory is on ``PATH``. Under PowerShell 7+
(``pwsh``) -- or any session where ``powershell`` isn't on ``PATH`` -- the
spawn dies and uv installation aborts.
The fix resolves the PowerShell host executable (preferring the absolute path
of the running host, then ``powershell``/``pwsh`` via ``Get-Command``) and
invokes *that* instead of a bare name. These tests lock that contract at the
source level (the script only runs on Windows, so there's no runner to
execute it on Linux CI).
