Adventure crafting: grant foraging XP per attempt, track lifetime crafts

Crafting was a downstream consumer of Foraging skill but never gave any
XP back, so the feedback loop was one-directional — only gathering
contributed to the level that gates better recipes.

Now: each auto-craft attempt grants Foraging XP (success > failure).
Per-tier values:
  tier 1:  +12 / +3
  tier 2:  +25 / +5
  tier 3:  +40 / +8
  tier 4:  +60 / +12
  tier 5:  +90 / +18

Successful T1 ≈ 30% of a Foraging Success haul; T5 ≈ 40%. Failures get a
small consolation grant — the attempt still produced practical knowledge
(and lost ingredients).

Schema: adventure_characters.crafts_succeeded INT for lifetime tracking.
Migration entry included.
