Gud Boi 7478478038 Lift `--ll`/`--tl` to plugin + `LogSpec` API
Two coupled changes that let downstream projects (eg. `modden`) inherit
the test-harness loglevel plumbing for free via
`tractor._testing.pytest`:

Plugin lift (`tests/conftest.py` → `_testing/pytest.py`),
- mv `pytest_addoption(--ll)`, the `loglevel` autouse
  fixture, and `test_log` fixture out of the test-suite-
  local conftest into the reusable plugin.
- add `--tl`/`--tractor-loglevel` as a DISTINCT flag from
  `--ll`: `--ll` is the consuming-project's OWN app
  loglevel (scoped to its pkg-hierarchy), `--tl` is the
  `tractor.*` runtime loglevel. `--tl` falls back to
  `--ll` when unset (preserves current `tractor`-suite
  behavior).
- add `testing_pkg_name` session fixture (default
  `'tractor'`) — downstream projects override to e.g.
  `'modden'` so `--ll` scopes to their own hierarchy
  instead of `tractor.*`.
- `loglevel` fixture now yields the resolved
  tractor-runtime level (passed to
  `open_root_actor(loglevel=<.>)` by `@tractor_test`)
  AND separately applies `--ll` to the
  `testing_pkg_name` hierarchy when that isn't
  `tractor`. `test_log` scopes the per-test logger to
  `testing_pkg_name`.

`tractor.log` "logging-spec" mini-DSL,
- `LogSpec = str|bool`. Accepted forms:
  - `True` → enable `pkg_name` root at `default_level`
    (fallback `'cancel'`).
  - `False` → no-op.
  - bare level eg. `'info'` → root-logger at that level.
  - `'sub:info,x:cancel'` → per-sub-logger filter-spec;
    each `<name>` is RELATIVE to `pkg_name` (must NOT
    include the pkg-token).
- `parse_logspec()` → `{sublog|None: level}` mapping.
  `None` key = root-logger. Mixed bare-level + filters
  in one spec is rejected w/ a helpful err msg; so is
  embedding the `pkg_name` token in a sub-name.
- `apply_logspec()` → `(primary_level, {name: log})`:
  parses then enables a `colorlog` stderr handler per
  named (sub)logger. Authoritative sub-logger filters
  get `propagate=False` so they don't double-emit
  through a parallel root-level handler.
- !GRANULARITY CAVEAT! sub-logger names match at
  sub-pkg granularity, not leaf-module — so `devx.debug`
  collapses to the same `tractor.devx` logger as a bare
  `devx`, and top-level lib modules (eg.
  `tractor.to_asyncio`) emit under the *root* logger
  rather than a phantom `to_asyncio` child. Documented
  inline on `LogSpec`.

Other,
- `tests/conftest.py` keeps a NOTE pointing to the
  plugin for future-debugging clarity (don't remove
  silently — the lift is the relevant signal).
