Replace idl/pump_fun_idl.json and idl/pump_fees.json with the latest from
pump-fun/pump-public-docs @ 7de0b95 (2026-04-23). pump_swap_idl.json was
already up to date.
Drops the idl/upstream/ vendor copy added in 7864504 in favor of
overwriting in place — the diff lives in git history. README updated to
point at pump-public-docs as the source of truth.

Update all 3 pump.fun IDL files (pump_fun, pump_swap, pump_fees) with
new cashback rewards and fee-sharing features. Fix IDL parser to handle
tuple struct types (OptionBool). Add bonding_curve_v2 remaining account
to all buy/sell instructions as required by the pump.fun program upgrade.
Key changes:
- Fix IDL parser crash on tuple struct fields (string vs dict)
- Add bonding_curve_v2 PDA derivation and append as remaining account
- Add is_cashback_coin field to TokenInfo and BondingCurve decoding
- Propagate is_cashback_enabled from CreateEvent/create_v2 to TokenInfo
- Conditionally include user_volume_accumulator for cashback sell txs
