## Prompt

Same `/code-review` follow-up session (PR #460). Finding #10:
the new `api/` autodoc reference pages surfaced 22 docutils
warnings sourced from informal reST in public docstrings. The
user opted to fix it on this branch,

> well we're on a clean main so why not just do these now too?

Goal: drive the docs build warning-free (24 -> 0) without any
code/behaviour change — docstring content only.

## Response summary

Surgical docstring-RST lint across 9 library modules + the one
offending `NEWS.rst` changelog entry,

- bullet lists given a blank line + base-column indent
  (`Context`, `Context.cancel_called`/`.cancelled_caught`/
  `.outcome`, `ActorNursery.cancel_called`, `query_actor`,
  `open_crash_handler`, the `#318` `NEWS.rst` entry),
- the under-short `Behaviour:` underline in `Context.cancel`
  demoted to a `**bold**` label,
- unbalanced/pluralized-role backticks fixed — closed the
  `wait_for_actor` summary backtick; applied the `` `role`\ s ``
  escaped-plural idiom in `gather_contexts`, `mk_pdb`,
  `MsgCodec`, msg `Error`, `open_context_from_portal`,
- the `|_` method-tree in `ContextCancelled.canceller` made a
  literal block (bare `|` was parsed as a substitution ref).

Verified: build `24 -> 0` warnings; `import tractor` clean under
`-W error::SyntaxWarning`; the `\ s` idiom renders as e.g.
"acms" (no backslash/space leak in HTML); `ruff` clean; diff
confirmed docstring-content-only.

Initial generation was delegated to a constrained subagent
(docstring-only edits + a rebuild-to-zero verification gate);
the orchestrator independently re-built, reviewed the full
diff, and added the `NEWS.rst` fix to reach zero.

## Files changed

- `tractor/_context.py`, `tractor/_exceptions.py`,
  `tractor/devx/debug/_post_mortem.py`,

  `tractor/msg/_codec.py`, `tractor/msg/types.py`,
  `tractor/runtime/_supervise.py`,
  `tractor/trionics/_mngrs.py` — docstring reST fixes,
- `NEWS.rst` — blank line before a bullet list in the `#318`
  entry.
