dsql 8a8d99bbb3 build: use git+https for inter-lib deps (docker ssh limitation)
docker builds can't use git+ssh (no ssh key / agent in the build), so the inter-lib
dependency references move to git+https (repos are public, anonymous clone). pins are
unchanged in target; bump to 1.0.2 so the https dependency spec ships under a new tag.
README install lines intentionally keep the ssh form for local/dev use.

dsql 52fea6e380 fix: pin inter-lib dependencies to their v1.0.0 tags
the v1.0.0 release still pinned pre-1.0.0 sibling tags, so a fresh install dragged in
stale transitive deps. update the pin(s) to the current v1.0.x release and bump this lib
to 1.0.1 so the corrected dependency chain ships under a new tag (v1.0.0 left intact).

dsql 6d4183948e fix: no sleep on exhausted final 429 attempt; correct errors.py doc (v0.1.6)
A 429 retry_after was slept immediately, including on the final attempt
that goes on to exhaust max_retries — a pointless wait right before
giving up. The wait is now carried in a per-call mutable cell and slept
at the start of the next attempt instead, so it's honored before every
attempt that actually runs and never after the last one.

errors.py's docstring claimed the exported error types cover the
missing-[discord]-extra raise path; that raise is a plain RuntimeError,
not one of these types. Reworded to match.

Compressed essay-length docstrings/comments across sender.py; no
behavior change. Verified against the aioproxies twin: aiowebhooks'
proxy-key normalization already routes zero-padded ports through
urlsplit().port (parses to int, no zero-pad on render), so host:080
and host:80 already collapse to one canonical key — no code change
needed there.

dsql 90f67cf9fa fix: bound 429 retry_after and retry connection errors without a proxy (v0.1.5)
A server-controlled 429 retry_after/Retry-After was slept verbatim with no
finiteness check or ceiling, so an inf or huge value (adversarial or a
ms-vs-s unit mismatch) could stall send() for hours outside max_retries
accounting. Non-finite values are now rejected and finite values clamped
to MAX_RETRY_AFTER (300s).

Connection/timeout errors with no proxy provider set failed one-shot,
contradicting the README's documented "normal retry" behavior and skipping
the single most retry-worthy failure class. They now raise the internal
_Retryable signal so commons.aretry retries them under max_retries, same
as a 5xx, while still returning a failed WebhookResult (never raising)
once retries are exhausted.

## Changelog
### v0.1.8
- Compressed 5 residual internal/trivial docstrings (`MAX_RETRY_AFTER`, `_Retryable`,
`_proxy_string`, `_retry_after`, `_attempt`) to one or two lines; no behavior change.
### v0.1.7
- Docstrings/comments compressed (module docstrings and internal-method prose); no
behavior change. Public method contracts (`Webhook.send`, `WebhookResult` field
docs) are unchanged.
- Em-dash characters replaced with hyphens across the source.
### v0.1.6
- **429 `retry_after` no longer sleeps on an exhausted final attempt:** the wait is
now carried to the START of the next attempt instead of slept immediately after
seeing the 429. Previously the last (exhausted) attempt slept the full
`retry_after` before giving up — a pointless wait since no retry followed. The
wait is still honored (additive with aretry's backoff) before every attempt that
actually runs.
- Docs: `errors.py` no longer implies the missing-`[discord]`-extra raise is one of
the exported error types — it's a plain `RuntimeError`.
- Docstrings/comments compressed; no behavior change.
### v0.1.5
- **429 `retry_after` bounded:** a non-finite server-controlled wait (`inf`/`nan`, from
the body `retry_after` or the `Retry-After` header) is now rejected outright, and a
finite wait is clamped to `MAX_RETRY_AFTER` (300s). Previously a bare `float()` parse
slept the value verbatim, unbounded and outside `max_retries` accounting — an
adversarial or ms-vs-s-misconfigured server could stall a `send()` for hours.
- **Connection/timeout errors now retry without a proxy provider:** previously
`aiohttp.ClientError`/`asyncio.TimeoutError` with no `proxies=` set failed one-shot,
contradicting both the README and the single most retry-worthy failure class. Now it
retries under `commons.aretry`'s backoff, capped by `max_retries`, same as a 5xx —
and still returns `ok=False` (never raises) once retries are exhausted. Proxy-rotation
behavior (burn + rotate, capped by `max_proxy_retries`) is unchanged when a provider
is set.
