v0.1.0 alpha - first playtest milestone

This is the first public alpha of Sky Frogs. Tiers 0-3 (Welcome / Cave / Geode / Bog) play end-to-end. Tier 4 (Tide) has its bridge chapter in place; Tide species content and Infernal / Void are forthcoming.

What's in

• Tier 0 (Welcome) - void starter island, dark-room slime farm, first Cave frog.
• Tier 1 (Cave) - the ore chain: iron, copper, gold, coal, redstone. New verb: storage upgrades (Sophisticated + Functional, quartz-free networks).
• Tier 2 (Geode) - the gem chain: lapis, tuff, calcite, amethyst, emerald, diamond. New verb: Mekanism power + machines (Metallurgic Infuser, Enrichment Chamber).
• Tier 3 (Bog) - the organic chain: dirt, mud, clay, moss, mycelium, lily pad, leather, feather, plastic, pink slime. New verb: Just Dire Things tier-1 progression + Building Gadgets 2.
• Slime Milk catalysts introduced at the Geode diamond gate (Count / Speed / Quantity / Infinite Count).
• Road to Tide chapter with the Industrial Foregoing spine and the Dissolution Chamber - the pack's slime engine. 21 chamber recipes ship for Cave / Geode / Bog (resource-threaded; iron bootstraps off bone meal).

Known limitations

• Tide species, Infernal, and Void are unbuilt (the questbook is honest about this).
• Some quest descriptions reference forward-looking content; flagged where it matters.
• Tank-based Slime Milk automation drops the variant on the FluidStack round-trip (tracked upstream as productive-frogs#129); use buckets via dispensers for now.
