feat(tma): Full mock game engine with AI opponent, economy, and audit fixes

[Glazlk]

Summary

Complete standalone mock game engine that simulates the full PvP user flow with an AI opponent. Replaces the dead socket.ts with mockGame.ts — the entire game is now playable in the browser without any backend, database, or blockchain connection.

This PR enables anyone to experience the full Elmental gameplay loop by simply running pnpm dev.

What's New

• Mock Game Engine (mockGame.ts) — AI opponent with 3 personalities (aggressive/conservative/adaptive), full commit→reveal→resolve flow, matchmaking simulation (5-15s search)
• Complete Economy — stake deduction on match-found, winner payout (pool - 5% rake), boost burn/return, transaction ledger
• Economy Breakdown on ResultScreen — shows stake, pool, rake, payout, boost status, net result
• Transaction History on ProfileScreen — replaces dead "Recent Rounds" placeholder
• Balance Protection — PLAY button disabled when insufficient ELM, shows "Need X ELM (have Y)"

Bug Fixes from Code Audit

Bug	Fix
Chaos mode always gave 10 regen	Now passes random chaosRoll (0-20) to calculateEnergy()
No round cap — infinite draw loop possible	MAX_ROUNDS (9) enforced, match ends by score comparison
EnergyBar broke at 120 energy (boost)	Dynamic maxEnergy based on boost status
Overclock warning badge was dead UI	Now works: visible when energy ≥ 0 but < move cost
MoveCard fully disabled on low energy	Now allows overclock plays (energy ≥ 0 but < cost)
Winning round overlay flashed for 100ms	1.5s delay before transitioning to ResultScreen
boost_burn transaction logged amount: 0	Correct negative amounts in all transactions
ProfileScreen always showed empty rounds	Live Transaction History from store
Negative ELM balance allowed silently	PLAY button disabled + clear messaging
Dead socket.ts (zero imports)	Deleted

• Hidden energy: opponent shows LOW/MED/HIGH indicator
• Round timer: 15s countdown, auto-submit on expire
• Round cap: MAX_ROUNDS (9) prevents infinite draws
• Boost: +20 starting energy, burn on loss, return on win
• Economy: 100 ELM stake, 200 pool, 5% rake, payout calculation
• ELO: rating changes on win/loss, K-factor 32
• Draw handling: refund on max rounds tie

How to Test

cd apps/tma && npx vite --host
# Open http://localhost:5173
# Click PLAY NOW → wait 5-15s → play match → see result + economy

Screenshots

Open the app and play a match — all 6 screens are fully interactive.

Test Plan

• Play match in Classic mode → verify regen (win+5, lose+15, draw+10)
• Play match in Hardcore mode → verify 0 regen
• Play match in Chaos mode → verify random regen (0-20)
• Enable boost → verify 120 starting energy + 10 ELM extra stake
• Win match → verify payout (190 ELM) + boost returned
• Lose match → verify stake lost + boost burned
• Check ProfileScreen → transaction history shows all events
• Balance below stake → PLAY button disabled
• Forfeit mid-match → stake lost
• npx vitest run → 78/78 shared logic tests pass
• npx vite build → builds successfully
