chore: spl, t22 test coverage

[SwenSchaeferjohann]

Syncs to light-protocol monorepo swen/refactor-trait branch and adds mixed mint support.

SDK/Trait Changes:

• Updated LightProgramInterface impl to new trait signature:

  • Instruction -> InstructionKind
  • get_accounts_to_update() -> get_accounts_for_instruction()
  • update() -> update_with_interfaces()

• Added get_cold_accounts_for_instruction() returning ColdAccountSpec::Pda / ColdAccountSpec::Mint

• Added decompression tracking: removes cold specs when account becomes hot

• impl. jup amm SDK trait

• Use local light deps

SPL/Token-2022:

• All token-transfer instructions accept optional spl_interface_pda_0/1 accounts and spl_interface_bump_0/1 params
• Instructions updated: initialize, deposit, withdraw, swap_base_input, swap_base_output, collect_protocol_fee, collect_fund_fee
• Token transfers use TransferInterfaceCpi.spl_interface() when SPL interface accounts provided
• Token programs passed per-token (supports Light, SPL, Token-2022)

Tests:

• lifecycle tests for all token combos: Light+Light, SPL+Light, SPL+SPL, SPL+Token2022, Light+Token2022
• • helpers
