feat: comprehensive balance pass (#239)

## Summary

Working through all 15 open balance tickets in a coordinated multi-pass approach.

### Pass 1 — Quest failure rates (closes #172)
- Capped all zone quest failure chances at 15% (down from up to 40%)
- Proportional scaling preserved (harder zones still fail more than easier ones)

### Pass 2 — Crystal economy (closes #165, #173, #215)
- Added `crystal_pulse` (3,000 crystals), `crystal_surge` (20,000), `crystal_tempest` (150,000) upgrades to fill the dead zone between 600 and 2M crystal sinks
- Bumped `click_deity`, `prestige_master`, and `prestige_legend` achievement crystal rewards (5K→15K, 5K→15K, 25K→75K)
- Added crystal rewards to `first_steps` (+5) and `goblin_camp` (+10) early quests

### Pass 3 — Runestone/prestige loop (closes #166, #170)
- Bumped `runestonesPerPrestigeLevel` from 15 → 20 (~33% yield increase for mid-game runs)
- Reduced `income_10` cost from 22,500 → 15,000 and `income_11` from 60,000 → 35,000
- Kept client/server parity: `runestonesPerPrestigeLevelClient` in tick.ts updated to match

### Pass 4 — Quest content (#175, #178)
- Both already resolved in commit 666a5b2: quests now reach 5e141 CP across reality_forge, cosmic_maelstrom, primeval_sanctum, and the_absolute — fully covering P60–P212

### Pass 5 — Daily challenges (closes #167)
- Added `crafting` as a new `DailyChallengeType`
- Added 3 crafting challenge templates (craft 1/2/3 recipes)
- Changed generation to guarantee: 1 clicks + 1 crafting + 1 from progression pool
- Added crafting challenge tracking in `craft.ts` (awards crystals on recipe craft)
- Stuck players now have 2/3 daily challenges always completable

### Pass 6 — Transcendence costs (#179)
- Already resolved in commit 666a5b2: echo meta costs are 15/45/100 (was 25/75/200)

### Also closed as stale
- #171 (milestone bonus already quadratic)
- #174 (production multiplier already 1.3^n)
- #176 (expanse_sovereign HP already at 3e39)
- #177 (recipe costs already in expected range)
- #178 (post-absolute quests already present)
- #179 (echo meta costs already reduced)
