Mycelium 0.1.0.3

Added

• Radial-Concentric Grid subtypes in the Massing Generator: full circular Civic Core, straight-sided Polygonal Radial, and a one-sided Fan Plan with a less-permeable rear sector.
• Diagonal Grid subtypes in the Massing Generator: Single Axis, intersecting Cross Axes, and an Orthogonal Overlay that cuts a wider diagonal boulevard through a regular grid.
• Irregular Grid subtypes in the Massing Generator: the backwards-compatible Recursive Orthogonal, seeded Deformed Grid, and offset-row Staggered Grid with T-junctions.
• Orthogonal Grid subtypes in the Massing Generator's nested right-click menu: Regular Grid, elongated Rectangular Grid, chamfered Cerdà Grid, and Hierarchical Superblock with wider primary streets around 3×3 groups of local blocks.
• Massing Generator right-click street-network selector with Irregular Grid (the backwards-compatible default), Orthogonal Grid, Diagonal Grid, and Radial–Concentric Grid modes. The selection is saved with the Grasshopper definition.
• Every published version now gets a git tag and a GitHub Release, cut by CI after Yak accepts the push, with the changelog section as its notes and both .yak distributions attached. Yak is still the only install channel; the tag exists so a version has an immutable ref pointing at the commit it was built from. Pre-releases are tagged too, marked as GitHub pre-releases.
• Re-release guard in the packaging workflow. A publish fails if the version's tag already exists on a different commit, or if Yak already holds both distributions — the "forgot to bump manifest.yml" case. On the dev dry-run it is a warning, not a failure, and a tag on the same commit (a re-run) and a partially-published version (the deliberate mac backfill) both stay allowed.
• .github/dependabot.yml, weekly on the github-actions ecosystem. NuGet is deliberately not enabled: the Grasshopper package pins the Rhino 8 ABI, so a bump there is a runtime change, not a build-tool one.

Changed

• Radial–Concentric Grid now terminates its spokes at a finite central civic/focal block and surrounding ring street. Spoke density is limited by available inner-ring frontage, avoiding unrealistic needle-shaped parcels at the center.
• GitHub Actions are pinned to full commit SHAs instead of the floating @v4 tags, so a re-pointed release tag cannot silently change what CI runs. The trailing # vX.Y.Z comment records the human-readable version.

Fixed

• Updating Mycelium Templates now clears downloaded template files before synchronizing, so changed .gh/.ghx content is fetched automatically. The redundant Force Refresh Template List command has been removed.

Install with Rhino's Package Manager, or yak install Mycelium 0.1.0.3.
