Phase 4: Cobblebase and Poke Power, gated behind progression

Adrian (2026-10-30): Cobblebase's skills stay in but gated behind
progression, power from an existing mod (Poke Power) also gated,
evolution stones as ores fine for now, balance fine and configurable.

Progression is the zones whose Alpha guardian a player helped beat
(Progress saved data; a guardian win records it and lists the unlocks).
The gate table is data (progression_gates/base.json): each of
Cobblebase's 44 skills needs a zone (or none), the Power Block needs the
Verdant Jungle. The companion mod wraps every Cobblebase skill executor
in a gate by reflection; a skill missing from the table stays off.
Operator command /cobblesurvival progress. Cobblebase's and Poke Power's
configs ship in the pack. Self-tests: gate coverage, a locked skill only
runs after its guardian, the Power Block waits for the Jungle guardian,
a guardian win counts as progress.
