pyr0ball 457276e302 feat: language mascot system + script-first architecture (v0.2.0)
Language mascots:
- 11 mascots across common/uncommon/rare/legendary tiers (Pythia, Asynclet,
  Bashling, Goroutling, Typeling, Vueling, Querion, Ferrix, Perlius,
  Cobolithon, Lispling)
- Full evolution chains for all mascots (16 evolutions total in catalog)
- Spawn via PostToolUse after language affinity milestones; probability
  scales with affinity level; only fires with no active encounter
- Passive strength reduction: each Write/Edit in the mascot's language
  ticks current_strength down (floor 5%, triggers re-announcement)
- Mascot-aware catch formula: base_rate + affinity_bonus (6% per level) +
  weakness_bonus + soft element gating via existing player_elements
- Language-themed weakening menu and catch failure messages in CLI
- Caught mascots stored as type="caught_language_mascot"; assignable as buddy
- UserPromptSubmit uses distinct 🦎 announcement with language context

Roster display:
- New "Language Mascots" section between core buddymon and caught bug monsters
- Language affinity table marks languages with spawnable mascots (🦎)
- Discovery counter now tracks both bug monsters and mascots separately

Veritarch (third evolution):
- Debuglin → Verifex (Lv.100) → Veritarch (Lv.200)
- TYPE FORTRESS / INVARIANT PROOF / ZERO FLAKE challenges
- xp_multiplier 1.7, catch_rate 0.90

Script-first architecture:
- All game logic extracted to lib/cli.py (~850 lines); SKILL.md is now
  a ~55-line relay — 88% token reduction per invocation
- CLI emits [INPUT_NEEDED] and [HAIKU_NEEDED] markers for interactive flows
- PostToolUse hook re-emits CLI stdout as additionalContext for inline display

Session XP fix:
- statusline.sh and session state now read from sessions/<pgrp>.json
  (per-window) with fallback to active.json; fixes stale XP in statusline
