fix(version): recognize PEP 440 development tags

Keep development-release tags discoverable across sequential bumps while preserving custom tag embedding and existing suffix behavior.

Constraint: Preserve custom tag formats and SemVer-compatible parsing.

Rejected: Replace the shared parser with the anchored PEP 440 reference regex | it breaks embedded tag formats and unrelated schemes.

Confidence: high

Scope-risk: narrow

Directive: Keep generated version forms round-trippable through TagRules.

Tested: uv run poe all; 446 focused tag, version, bump, and changelog tests; exact uv-provider sequential bump regression; git diff --check.

Not-tested: Full tox matrix across every supported Python version and operating system.
