v0.7.8 — CPMM creator fee share and RPC validation

CPMM creator-fee protocol share and mainnet replay validation

Updates collection account lists, creator share PDA derivation and AmmConfig share-rate decoding. Fixes failed-transaction event suppression and instruction/account preservation.

Adds RPC discovery/capture/replay examples and independent validation of 13 mainnet transactions, covering 17 target operations. CPMM exact-output and permissionless collection lack real samples; historical payout-share calculations are not covered.

Validation: 405 library tests and 9 mainnet corpus tests passed; crates.io package verification passed.
