Subject: [PATCH 1/2] Fix > comparison for versions with dev+local segments

The greater-than specifier incorrectly rejected versions like
4.1.0a2.dev1235+local against >4.1.0a2.dev1234. The local version
guard used _base_version which strips pre/dev/post segments, making
different dev versions appear equal. Replaced with _public_version
which only strips the local segment, correctly identifying when a
local version genuinely differs from the spec version.

Fixes #810

Subject: [PATCH 2/2] Add tests for > specifier with local+pre/dev/post
 segments

Cover the behavior change from _base_version to _public_version by
testing that local versions with varying pre, dev, and post segments
are correctly accepted or rejected by the > operator.

True cases: local versions whose public part genuinely exceeds the spec
(e.g. 1.0a2+local > 1.0a1, 1.0.dev2+local > 1.0.dev1).

False cases: local versions whose public part matches the spec exactly
(e.g. 1.0a1+local should not match >1.0a1).
