bump version to 0.3.0

[atomikpanda]

Summary

Bump mship to 0.3.0 and fix version drift.

pyproject.toml was at 0.2.0 while src/mship/__init__.py __version__ had silently lagged at 0.1.0 (nothing consumed it, so nothing caught the drift). Both are now 0.3.0, and a new tests/test_version.py asserts mship.__version__ == pyproject [project].version so they can't diverge again.

0.3.0 reflects this cycle's feature work (bootstrap, cloud auth, the enforcement gate, spec list/show + lifecycle transitions, journal/build/etc.).

Test plan

• tests/test_version.py::test_version_matches_pyproject (new) passes.
• Full suite green via mship test.

Greptile Summary

This PR synchronizes the package version to 0.3.0 across both pyproject.toml and src/mship/__init__.py, and adds a regression test to prevent the two from diverging again.

• Version bump: pyproject.toml updated from 0.2.0 → 0.3.0; __version__ in src/mship/__init__.py corrected from the stale 0.1.0 → 0.3.0.
• Guard test: tests/test_version.py reads pyproject.toml via tomllib (stdlib since 3.11, safe given requires-python = ">=3.14") and asserts mship.__version__ matches, preventing silent drift in future.

Confidence Score: 5/5

Safe to merge — all three changes are mechanical version string updates plus a straightforward regression guard.

The change touches only version strings and adds a test that reads a static file and performs a single equality assertion. There is no runtime logic, no API surface, and no side-effects to evaluate. The guard test itself is well-formed: it uses tomllib from the standard library, explicitly passes encoding='utf-8', and correctly navigates to pyproject.toml via parents[1].

No files require special attention.

Important Files Changed

Filename	Overview
pyproject.toml	Version bumped from 0.2.0 to 0.3.0; no other changes.
src/mship/init.py	version corrected from the stale 0.1.0 to 0.3.0, now in sync with pyproject.toml.
tests/test_version.py	New regression guard that asserts mship.version equals pyproject.toml's project.version; uses UTF-8 encoding and stdlib tomllib correctly.
