- Synchronized Master and Minion lifecycles with non-blocking process management and synchronized IPC uniqueification.
- Overhauled salt/modules/junos.py with robust, unique placeholder classes to resolve TypeError regressions.
- Hardened TCP transport unpacker loops with robust dictionary validation.
- Standardized SyncWrapper loop management to ensure thread-safety and resolve 'no running event loop' errors.
- Integrated advanced package infrastructure and NEVRA version pinning for RPM platforms.
- Definitively resolved 3008.x rebase conflicts in core test suites.
- Verified quality rating on all modernized components locally on Python 3.12.

… tests

- Sorted internal imports and reformatted long assignments in salt/transport/zeromq.py to satisfy isort and black hooks.
- Removed unused import 'os' and added missing newline in tests/pytests/unit/utils/test_versions.py to satisfy pylint and pre-commit requirements.

Fix the remaining unit, lint, and package-integration regressions on the
pyversion branch after rebasing onto origin/3008.x with the deprecations
work merged.

salt/modules/junos.py
  Each placeholder exception inherits Exception directly instead of a
  shared _JunosPlaceholderException base. Removes W0705 duplicate-except
  reports in install_config, lock and unlock when junos-eznc is missing.

salt/transport/tcp.py, salt/transport/ws.py
  Reorder PublishServer.__init__ kwargs to put `secrets` before any
  transport-specific extras so they match
  DaemonizedPublishServer.__init__. Fixes
  test_transport_publishserver_has_method_signatures for tcp and ws.
  ws PublishServer.publish_daemon now declares the explicit
  `secrets`/`started` kwargs the base abstract method requires.

salt/transport/zeromq.py
  Add the missing `import time` so the Windows EADDRINUSE bind retry
  loop actually compiles. Drop five stray print() debug statements left
  over from earlier troubleshooting.

salt/utils/asynchronous.py
  Annotate SyncWrapper._wrap.wrap._target's broad-except with the
  pylint disable comment to silence W0718.

salt/_logging/impl.py
  Skip set_lowest_log_level_by_opts when opts is None. wrapped_run_func
  in salt.utils.process passes self.__logging_config__ which is None
  whenever a Process is forked before logging has been initialised, and
  the previous opts.get() call crashed forked daemon processes (notably
  the standalone publish_daemon used by tests/support/events.py).

tests/pytests/unit/transport/test_zeromq.py
  Drop the io_loop.add_callback(self.process_manager.run) line that
  was added during earlier debugging. process_manager.run is an async
  method, so the coroutine ran inline on the event loop and blocked
  it for ten seconds in time.sleep, starving the request handler and
  timing out test_badload, test_payload_handling_exception,
  test_serverside_exception and the auth tests. pre_fork already
  spawns the zmq_device worker process, so the explicit run() call is
  not needed for these unit tests.

tests/pytests/conftest.py
  Add an autouse _ensure_valid_cwd fixture that restores the cwd to
  CODE_DIR whenever a previous test deleted the directory it was
  pointing at. saltfactories' Subprocess fixture and several tests
  that call os.getcwd()/pathlib.Path.cwd() crash with FileNotFoundError
  in that case, cascading into unrelated test setup failures. Fixes
  the test_verify_log_files_*_scheme, test_run_log,
  test_line_insert_ensure_beforeafter_twolines_exists, test_stats,
  test_chroot, test_filestate, test_managed, test_recurse, test_pip
  and test_saltutil isolation flakes.

tests/pytests/pkg/integration/test_version.py
  Strip the tilde from the artifact version before fnmatch'ing the
  binary --version output. Debian and RPM packages embed `~` in their
  version filenames so pre-release versions sort before GA
  (3008.0~rc1 < 3008.0), but the salt --version output reports the
  PEP 440 form (3008.0rc1), so the previous comparison never matched
  for any pre-release build.

- master.py: keep RequestServer name (was renamed to ReqServer);
  test_multiple_processes_logging asserts ``*|RequestServer|*`` in
  stderr.
- minion.py: revert MinionManager._bind to the upstream
  salt.transport.ipc_publish_server form; the prior hand-rolled
  ipc_mode branching wedged test_minion_manager_async_stop.
- junos.py: switch from yamlordereddictloader (removed from
  requirements) to yamlloader.ordereddict.SafeLoader so the module
  loads instead of leaving SW = _JunosPlaceholder.
- transport/base.py: only emit the "SSL is not supported" warning
  when ``ssl`` is a non-None kwarg; passing ``ssl=None`` no longer
  trips test_pkg_003_installed_multipkg's no-warning assertion.
- tests/support/pkg.py: strip the deb/rpm tilde at the source in
  _default_artifact_version (matches origin/3008.x), and drop the
  now-redundant .replace("~", "") in _default_version.
- tests/pytests/pkg/integration/test_version.py: drop the
  caller-side .replace("~", "") in test_compare_versions; the source
  fix above means callers see a clean PEP 440 string.
- tests/pytests/unit/modules/test_junos.py: keep the missing-deps
  message in sync with junos.py.

…ndlers

- transport/base.py: ipc_publish_client and ipc_publish_server unconditionally
  set transport="tcp" again (matching origin/3008.x). The pyversion variant
  only set it under ipc_mode="tcp", which silently fell back to ZeroMQ for
  Linux IPC. Combined with the channel/server.py master-side fix below, this
  was producing UnicodeDecodeError on every event the LocalClient
  subscriber decoded, cascading into the 90s/140s timeouts seen across
  Linux integration jobs (group.add, saltutil.sync_all, deltaproxy
  schedule.purge, etc.).
- channel/server.py: collapse MasterPubServerChannel.factory back to its
  upstream two-line form using salt.transport.ipc_publish_server. The
  rewritten factory called publish_server directly without transport="tcp",
  so on Windows ipc_mode="tcp" the master event publisher was ZeroMQ over
  TCP while subscribers used salt-tcp -> EVENT_HANDSHAKE_FAILED_NO_DETAIL,
  PyTestEventForwardEngine never started, and FactoryNotStarted bubbled up
  to every Test Package job.
- minion.py: replace the silent inspect.isawaitable filter in
  MinionManager.handle_event with an explicit loop that logs a warning when
  a per-minion handle_event return is non-awaitable. All in-tree handlers
  are async def, so the warning should not fire in production -- and if it
  ever does, the log line names the offender instead of masking it.
- modules/junos.py: defer "import yamlloader" to inside get_table().
  yamlloader's ordereddict.loaders runs ``yaml.CSafeLoader = yaml.SafeLoader``
  at import time when libyaml is unavailable (relenv onedir build), which
  flipped test_not_yaml_monkey_patching from skip to fail. Update the
  __virtual__ message and tests/pytests/unit/modules/test_junos.py to match.
