Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

environment:
  sdk: ^3.12.0

🐛 Fixed

Add well-known program, sysvar, SPL, Metaplex, and token mint address constants

Add centralized address constants to solana_kit_addresses so that any package can reference well-known on-chain addresses without importing the full domain package or hardcoding strings.

New exports:

• program_addresses.dart — All Agave/Solana native program addresses (system, ALT, BPF loaders, compute budget, config, stake, vote, etc.)
• sysvar_addresses.dart — All sysvar addresses (clock, rent, recentBlockhashes, fees, rewards, etc.) plus the sysvar owner address
• spl_addresses.dart — SPL program addresses (Token, Token-2022, ATA, Memo, Memo Legacy)
• metaplex_addresses.dart — Metaplex program addresses (Token Metadata, Bubblegum, Auth Rules, Core, SPL Account Compression, Noop)
• well_known_addresses.dart — Well-known token mint addresses (Wrapped SOL, USDC, USDT)

Also re-exports from solana_kit_address (Address type, codecs, comparator, PublicKey) and solana_kit_address_constants (well-known address constants).
