Mycelium 0.1.0.1

Changed

• Yak package name capitalized mycelium → Mycelium (server lookups are case-insensitive, so this is cosmetic — matches the manifest/repo casing everywhere, Eddy3D-style).
• Template component now syncs from a branch matching the running assembly version (was hardcoded to main); quick_start.ghx moved out of the plugin into Mycelium-Templates, no bundled templates ship anymore.

Removed

• GitHub Release / Pre-Release workflows (tagged zip releases on GitHub). Yak remains the only distribution channel.

Install with Rhino's Package Manager, or yak install Mycelium 0.1.0.1.

Tag and release backfilled after the fact; the plugin was published to Yak at the time from this commit.
