- Use protocol_params.creator_vault for buy/sell when non-default to avoid
ConstraintSeeds (2006) when gRPC/event creator drifts from on-chain bonding curve
- Preserve event creator_vault in PumpFunParams::from_trade/from_dev_trade instead
of always overwriting with PDA(creator)
- Fee recipient: prefer gRPC fee_recipient; else random from CURRENT_FEE_RECIPIENTS
pool (standard) or MAYHEM pool, matching @pump-fun/pump-sdk fees.ts
- Add cold-path helpers: extend_bonding_curve_account_instruction, PUMP_BONDING_CURVE_MIN_DATA_LEN
Made-with: Cursor
- PumpFunParams::from_trade/from_dev_trade: add mayhem_mode Option; infer Mayhem
via is_mayhem_fee_recipient when None (fixes fee recipient / NotAuthorized 6000
when AMM protocol fee pubkey is used).
- Add is_mayhem_fee_recipient and is_amm_fee_recipient helpers in pumpfun utils.
- Bump solana-* crates to 3.1.12; align tonic/prost; use solana-message for
AddressLookupTableAccount; add solana-system-interface 3.0.
- Update examples and latency script for new PumpFunParams signature.
- SWQoS and transaction builder adjustments for dependency changes.

- Add `mev_protection: bool` to `TradeConfig` and `InfrastructureConfig` (default: false)
- Astralane QUIC: switches to port 9000 (MEV-protected endpoint) when enabled
- BlockRazor HTTP: uses `mode=sandwichMitigation` query param when enabled
- BlockRazor gRPC: uses `mode=sandwichMitigation` when enabled
- Add `SWQOS_ENDPOINTS_ASTRALANE_QUIC_MEV` constants (port 9000) to `constants/swqos.rs`
- Fix `astralane_quic.rs` IP candidates to use the actual port from the address (supports both 7000 and 9000)
- Refactor `TradeConfig` to builder pattern via `TradeConfig::builder()`
- Introduce `TradeConfigBuilder` with all optional fields and clear defaults
- `TradeConfig::new()` kept as a shortcut (calls `builder().build()`) for backward compatibility
- Remove old `with_wsol_ata_config` / `with_check_min_tip` / `with_swqos_cores_from_end` / `with_mev_protection` chain methods
- Update all 16 examples to use `TradeConfig::builder()` with commented-out options so users can discover all available settings at a glance
- Update README.md and README_CN.md code snippets to use builder pattern

Changes to src/utils/calc/common.rs:
- Add MAX_SLIPPAGE_BASIS_POINTS constant (9999 = 99.99%)
- Clamp basis_points in calculate_with_slippage_buy to prevent amount doubling
Changes to src/instruction/pumpswap.rs:
- Fix WSOL wrap amount calculation for exact vs non-exact input modes
- Use input_amount for exact mode, sol_amount for non-exact mode

- Store gRPC client as Arc<ArcSwap<BlockRazorGrpcClient>> so BlockRazorBackend
can derive Clone (ArcSwap does not implement Clone).
- Cloning the outer Arc gives owned handles for tokio::spawn in start_ping_task,
fixing E0521 (borrowed self escaping to 'static future).

Implement lock-free reconnection mechanism using ArcSwap to maintain high
performance for transaction sending while providing automatic recovery
from connection failures.
Key improvements:
- Add automatic reconnection with exponential backoff (1s -> 60s max)
- Use ArcSwap for lock-free atomic reference swapping
- Zero overhead for send_transaction path: only atomic load operation
- Background health check every 30s triggers reconnection on failure
- Reconnection success resets backoff delay to 1s
This ensures transaction sending remains fast (no lock contention) while
providing automatic recovery from network issues or server restarts.
Inspired by the proven reconnection pattern in sol-parser-sdk.
