trac-msb v0.2.10

Changes

• Reworked runtime configuration and network selection (PR #469, #488, #485; contributors: @leonardotc): moved network, RPC, rate-limit, and connectivity settings into config, added environment-aware startup resolution with
  mainnet / development / testnet1, updated wallet integration to trac-wallet 1.0.2, and restored mainnet as the default network.
• Improved storage layout and node startup (PR #498 plus testnet bootstrap update; contributors: @leonardotc): introduced --stores-directory, made store names network-defined and non-overridable, ensured corestore directories are
  created automatically, and refreshed bootstrap configuration for testnet.
• Expanded and hardened the v1 RPC API (contributors: @lucasfernandes , @leonardotc): added GET /v1/health, standardized typed RPC errors for validation, broadcast, and not-found cases, improved balance and transaction handlers, and
  fixed acceptance-tested behavior for /v1/balance, /v1/tx/:hash, /v1/tx/details, and /v1/broadcast-transaction.
