Fixes #62

Part of #53.

What this does

The second of the pull requests stacked on #55 that fix the Ruff findings #55 leaves ignored: the 458 findings in D (pydocstyle), after which pyproject.toml no longer ignores the family. Stacked on #58. Only docstrings change.

• D209 (58) and D202 (40): Ruff's fixes put closing quotes on their own line and remove the blank line after a function's docstring.
• D102 (110), D103 (44), D107 (31), D101 (14), D105 (10): new docstrings for the public methods, functions, __init__ methods, classes and magic methods that had none. Each was written from the code it describes: what it returns or changes, and the errors it raises where that matters. In tests, D1 is exempt, as in both services, so these are all in src, packages, scripts, tools and the root conftest.py.
• D401 (81), D205 (69), D404 (1): summaries. Each summary is now one sentence in the imperative mood on the first line, and the rest of the old docstring is kept as its description. Test docstrings that began with only a review reference keep that text in full as the description, under a summary that says what the test checks.
• Two placeholder bodies go. In BuildCompleted (the interface's telemetry commands) the docstring replaces pass, and in the Orrery GraphTransport protocol it replaces ..., since Ruff's PIE790 flags a placeholder next to a docstring. The host's ServiceModule and the telemetry Transport protocols keep their ... bodies after the new docstrings, which Ruff accepts.
• One description is reworded: default_handover_database_path in the interface package said "spool database"; it now says "event queue file", as the emitter's documentation calls it.
• Ruff no longer ignores D. Every summary fits on the first line; D401 checks the mood of function and method summaries only, so class, property and module summaries may be descriptive phrases.

Four helper agents wrote the docstrings, one per area (the interface package; the Hugging Face, submissions and Orrery services; core, host and telemetry; tests, scripts and tools), from one brief. I checked their work as a whole: see the record below.

Test-first record

There is no red step, since nothing changes behaviour.

Commit	Result
fbc62d2 The docstrings	ruff check . and ruff format --check . pass with D selected (except D203 and D213, as in both services). All five guards pass with GITHUB_BASE_REF=main. With docstrings and placeholder bodies removed, the syntax tree of each of the 84 changed modules is identical to the base branch's, so no code, import, name or comment changed.
f667e59, 159f95f Merges of #55's round 2 and #58's round 1	ruff check . and ruff format --check . pass; the merged code needed no new docstrings.

0b3475a Docstring corrections

The interface's transition_stage and StageTransition now say how each status is handled: an update for another stage finishes the current one, only a start makes a stage current, and completed or failed ends the current stage. The calibration methods, in the interface and the emitter client, say that only calibration_epoch events are recorded, and that the move to the calibrating stage happens only when the run is not there already. Four smaller corrections; the fragment says only function and method summaries are imperative. ruff check . and ruff format --check . pass; with docstrings removed, the 6 changed modules match the previous head.

No test was run: the only changes to test files are docstrings, which the syntax-tree comparison shows. CI runs the tests.

CI

No workflow, trigger or script changes, and no environment variable or secret is read differently.

Release

The fragment is changelog.d/ruff-docstrings.changed.md, a patch bump: merging releases the next patch version of both distributions, whose docstrings change.
