a portless proxy url produced host::user:pass / host: (extra colons), breaking the identity match against the provider pool. the port colon is now omitted when there is no port, mirroring aioproxies' canonical key.

the clock= constructor param was stored (self._clock) but never read — the 429
retry_after wait uses asyncio.sleep directly. it was dead code, and the CLAUDE.md
wrongly claimed it made 429 timing test-controllable. remove the param + the unused
time import, and correct the doc (tests patch commons.retry's sleep + sender.asyncio
.sleep, not a clock seam). bump the commons pin to v0.2.1 (retry attempts floor).
verified: clock param gone, constructs fine, 18/18 fix harness intact.
