0xfnzero d711346c55 fix(meteora-damm-v2): use correct token program for output ATA creation 
- Pass token_a/token_b program based on swap direction (is_a_in) when
  creating the output mint ATA in buy flow, matching ATA address derivation
  for SPL Token vs Token-2022 mints.
- Resolve token_a_program and token_b_program from on-chain mint account
  owners in MeteoraDammV2Params::from_pool_address_by_rpc instead of
  hardcoding the classic SPL Token program.

Fixes incorrect ATA creation for Token-2022 output mints (issue #99).

Wood 9f79e865ab perf: P0/P1/P2 low-latency and maintainability improvements 
P0:
- blockhash/nonce: get_transaction_blockhash returns Result; buy/sell entry validation
- Bonk sell: remove RPC get_token_balance from build path; require caller to pass input_amount
- Hot path: drop redundant dex_type/protocol_params clone; tip via sol_f64_to_lamports (no String)
- compute_budget cache uses Arc; extend_compute_budget_instructions avoids SmallVec clone

P1:
- middleware protocol_name takes &str; executor destructures result once to avoid signatures/submit_timings clone
- Error messages include dex context; params use Copy for Pubkey; pumpswap utils clone only Pool for pools[0]

P2:
- transaction_pool capacity constants; TIP_ACCOUNT_CACHE marked allow(dead_code)
- Fix error copy in raydium_amm_v4 / meteora_damm_v2 to correct protocol names
