Prepare HSSM 0.5.0 release

[AlexanderFengler]

Version bump and changelog for the 0.5.0 release.

• 0.4.0 → 0.5.0 — minor, not patch: three new built-in models across this cycle (gamma_drift from Add gamma_drift as a built-in approx_differentiable model #1248, gamma_drift_angle feat: add gamma_drift_angle as a supported model #1296, angle_extended feat: add angle_extended as a supported model #1298), the ssm-simulators>=0.14.0 floor bump, and the Unreleased section already contains one documented breaking change (hssm.load_data() with no argument now raises).
• Restores the two model changelog entries (9, 10): both PRs merged minutes before their changelog commits landed, so those commits were orphaned on the closed branches. Content identical to what rode the PRs.
• Retitles ### Unreleased → ### 0.5.0 per the changelog convention.
• Note: a stray v0.4.1 tag exists with no matching PyPI release (PyPI latest is 0.4.0); 0.5.0 supersedes it and no reconciliation is needed beyond not reusing the number.

mkdocs build passes locally (exit 0). Model-config tests pass against released ssm-simulators 0.14.0.

Do not publish the GitHub release until angle_extended.onnx is on franklab/HSSM — main currently advertises a built-in whose artifact only exists on staging; the promote is queued and must land first. gamma_drift_angle.onnx is already live in production.

This updates the package and changelog for HSSM 0.5.0, but the release heading violates the documentation heading hierarchy and can fail documentation linting. Correct the heading before merge.
