chore(deploy): mainnet fresh-deploy path + repoint to new mainnet contracts (#71)

- Deploy.s.sol: gate MarketSeed/bootstrapMarket behind non-mainnet. On
  Gravity mainnet (chain 127001) switch GTreasury to withdraw mode
  (faucet OFF -> withdraw ON) so no unbacked G can be minted on the
  full-backed mainnet economy.
- Repoint default Router to the freshly deployed mainnet proxy
  0x13860c81003e1d11E8C8576F995a68b02c750A59 across frontend config,
  MCP server defaults (src + rebuilt zero-install bin bundle), README,
  and the play-skill connect docs.
- frontend: format wei-denominated gBalance for display (1 G = 1e18),
  fixing the G column now that mainnet runs the wei economy.
