When using multiple SWQOS channels with durable nonce, if one channel's
transaction lands on-chain but fails (e.g., ExceededSlippage), the nonce
is consumed and other channels cannot succeed.
Previously, the SDK would wait for all channels to timeout (~15s) before
returning, and would often return a generic "timeout" error instead of
the actual on-chain error.
This fix:
- Adds `landed_on_chain` field to TaskResult to track if tx landed
- Adds `is_landed_error()` to detect on-chain failures vs timeouts
- Adds `landed_failed_flag` to ResultCollector for early exit signaling
- Returns immediately with the actual error when a tx lands but fails
This makes behavior consistent with the success case - both return
immediately once the nonce is consumed.
Benefits:
1. Get the actual error (e.g., ExceededSlippage) instead of timeout
2. Return in ~1s instead of ~15s
3. Enable faster retry logic for callers

- Remove deprecated wsol_use_seed and mint_use_seed parameters
- Fix fast_fn module exports
- Define minimum tip constants for each SWQOS provider (JITO, NextBlock, Node1, etc.)
- Add dynamic filtering in execute_parallel to skip transaction building when tip is below provider's minimum
- Add missing SWQOS_ENDPOINTS_ASTRALANE constant
- Ensure SWQOS clients are always initialized but transactions are conditionally built based on current tip amount
Major changes:
- Bump version from 3.3.0 to 3.3.1
- Update GasFeeStrategy API with min/max data size parameters
- Enhance trade return values with Optional<anyhow::Error> in buy/sell/sell_percent methods
- Fix PumpFun Mayhem mode fee recipient constant bug
- Standardize gas fee strategy parameters across all examples
- Update all examples to handle new triple return value (bool, Signature, Option<Error>)
Replace the global AddressLookupTableCache with a direct fetch function to simplify address lookup table management. This change improves code maintainability by removing global state and makes the API more explicit.
Key changes:
- Remove AddressLookupTableCache and AddressLookupManager
- Add new fetch_address_lookup_table_account function
- Update TradeBuyParams and TradeSellParams to use AddressLookupTableAccount instead of Pubkey
- Update all examples to use the new direct fetch approach
- Update documentation to reflect the simplified workflow
