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.
