The "Toward capability-based msging" section only pointed at the
`#196`/`#36` epics. Fold in the concrete recent state,
- `#365` as the most recent step: driving the whole `pld_spec` off
plain type-annotations (e.g. annotating a context's
`open_stream()` with `msgspec.Struct` subtypes) rather than
explicit `pld_spec=` kwargs.
- clarify that the decorator-level `@tractor.context(pld_spec=...)`
is already the higher-level path (vs the lower-level
`tractor.msg._ops.limit_plds()` escape hatch), pointing at
`tests/msg/test_pldrx_limiting.py` + `test_ext_types_msgspec.py`
which exercise both.
- `#376` (from @guilledk, `auto_codecs` branch) as the drafted
public factory API for the `enc_hook`/`dec_hook` pair (today only
reachable via `tractor.msg._ops`).
Addresses the caps-based-msging bullet in #472.
