Add a runnable `examples/dedicated_registrar.py` + a "A dedicated
registrar" subsection in `guide/discovery.rst` demoing the
registrar decoupled from any app tree's root: boot a bare
`tractor.run_daemon([], registry_addrs=[...])` as its own process
(a root actor that does nothing but hold the registry), point the
app tree at the same `registry_addrs`, and discover a service
*through* that external registrar.
This is the buildable-today form of the #472
"Registrar-as-subsystem (not the root actor)" bullet. Two
constraints are called out inline as follow-ups:
`enable_transports` is single-proto per runtime (no multi-backend
registrar yet), and a registrar can only be a root (no `actor_cls`
hook on `start_actor()` to spawn one as a subactor).

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.

Address the actionable findings from the `/code-review` pass
(#1-6); the d2-ext + docstring nits (#7-10) are left for a
follow-up.
Deats,
- `uds_transport_actor_tree.py`: `portal.chan.raddr.sockpath` is
the *shared listener* socket (named for the root registrar), NOT
the child's path — relabel it + lead with the per-child peer pid,
and stop claiming it's the child addr in the docstring,
- `docs.yml`: scope the `pages` `concurrency` group to the `deploy`
job w/ `cancel-in-progress: false` so a PR build can't cancel an
in-flight production deploy,
- `architecture.rst`: `'subint'` is not a selectable `start_method`
on this branch (`SpawnMethodKey` lacks it) — reframe as
in-development/roadmap,
- `context.rst`: `StreamOverrun` isn't re-exported from `tractor`;
point at `tractor._exceptions`,
- `debugging/`: sweep the 3 literalinclude'd examples off the
deprecated `.result()` -> `.wait_for_result()`,
- `quickstart.rst`: proc-title is `name@pid` (per `Aid.reprol`),
not `@uuid`.
NOTE, the `debugging/` examples are pexpect-tested; re-run
`tests/devx/test_debugger.py` for them.

Replace the ancient `docs/index.rst` (still teaching
`tractor.run()`, `@stream` + arbiters..) with a full ~32 page tree
teaching ONLY the current api (`.wait_for_result()`, registrar
naming, `@context` + `open_context()` as the core model),
- landing: hero example, feature cards + canon links,
- `start/`: install + a 4-example quickstart on-ramp,
- `explain/`: an "SC across processes" essay distilling the essence
per #157's orig ask + a runtime architecture tour,
- `guide/`: 12 task-focused pages incl the flagship multi-process
debugging walkthrough, `Context` + `MsgStream` deep-dives,
cancellation semantics (self-vs-cross cancel rules), discovery,
infected `asyncio`, typed msging + the #126 testing-tips page,
- `api/`: 10 curated autodoc pages (all targets import-verified vs
the reorg'd subpkg tree),
- `project/`: changelog include, ported dev-tips (drops old
`docs/dev_tips.rst`) + roadmap.
Every code block is a `literalinclude` from `examples/`
- zero duplication, all CI-run - w/ `d2` figs floated
into the RHS margin per the 3-col design. Build is green; the 24
remaining warnings all source from lib docstring rst-isms or legacy
`NEWS.rst` content.
Substantially resolves#157 (refine round pending); chips at #175 +
#126.
