Layer8Problem-AP v0.4.0

Added

• Per-character Progressive Affection items: Progressive Affection (Kevin),
  (Chantal), (Egon), (Elster), (Markus), (Gabi). Three copies of each
  are placed in the pool. The character's tier locations are now gated:
  • 1 copy unlocks <Character> - Friend
  • 2 copies unlock <Character> - Ally
  • 3 copies unlock <Character> - Bestie
• Goal-aware completion logic in set_rules(). The world now honors the
  YAML goal option for completion:
  • legendary_set (default): collect all 9 legendary items.
  • all_achievements: all 24 achievement locations reachable.
• Filler-only items (Donut, Bubble Wrap, Stress Ball) now have stable
  reserved IDs in the range AP_BASE + 1300...

Changed

• Progressive item ID layout reassigned:
  • Progressive Affection (Kevin..Gabi) -> AP_BASE + 1200..1205
  • Progressive Difficulty -> AP_BASE + 1206
• Item pool composition is now exact (no filler padding under default settings):
  • 9 legendary + 18 normal + 2 Progressive Difficulty + 18 Progressive
    Affection (6 chars x 3) = 47, matching the 47 locations.

Removed

• Generic Progressive Affection item (replaced by the six per-character
  variants above).
• Donut, Bubble Wrap, Stress Ball removed from the guaranteed
  NORMAL_ITEMS pool. They still appear via the filler pool.
• Progressive Difficulty item removed. The in-game day = difficulty, and
  there are only three days. Stacking a difficulty item never matched the
  game model. The starting day is now fixed per slot via the new
  starting_day YAML option in the .apworld.
• survive_week goal removed. With three playable days, "survive N days"
  doesn't fit. Only legendary_set (default) and all_achievements remain.
• 0.3.x and 0.4.0-draft seeds are not compatible. Regenerate.

Breaking

• Seed incompatibility: old 0.3.x seeds will not roll on 0.4.0 and vice
  versa. Generator and client must be updated together.
• Client must map six new item names (Progressive Affection (<Char>))
  and remove the generic Progressive Affection mapping.
• Affection tier locations are now gated. Even Friend requires at least
  one Progressive Affection copy. Existing playthroughs / logic reports
  generated against 0.3.x will differ.

Reserved for v0.5.0

• Negative affection tiers (e.g. Disliked, Hated) - will expand both the
  location and item pools, opening room for additional normal items.
