chore: bump version to 0.1.0 [skip ci]

[MISC] Drop the `none` bump and clean up after a failed publish (#9)

* ci: drop the `none` bump and start the committed version at 0.0.0

`none` existed so the first release could publish the 0.1.0 already in the
file. With nothing published yet the file can start at 0.0.0 instead, and the
first release is an ordinary `minor` bump. After that `none` has no use: the
tag guard refuses a version already released, and so does PyPI.

* ci: keep the committed version at 0.1.0

The first release is being published from the version already in the file,
so it stays; only the `none` option goes.

* ci: leave nothing behind when the publish fails

A publish that failed left the tag and the draft release in place, and for a
stable release the bump commit already on main; the next dispatch then
stopped on the tag guard until all three were removed by hand.

The bump commit now reaches main only after the publish, carried until then
by the tag alone, and a step that runs on failure removes the tag and the
draft release. It sits directly after the publish so a failure later in the
run, with the version already on PyPI, cannot remove the tag that names it.

* ci: keep the tag when a failed publish still put the version on PyPI

The wheel and the sdist upload one after the other, so a publish can fail
with the version already served. The cleanup now asks PyPI first and leaves
the tag and draft release in place when it is.

* chore: start the committed version at 0.0.0

With nothing published, the first release is an ordinary `minor` bump rather
than a special case.
