sol-parser-sdk v0.7.5

Fixes Meteora DAMM v2 swap account recovery (solana-streamer issue #82). Matches real swap/swap2 instructions by discriminator, pool, and program; backfills mints, vaults, payer, token programs, and optional referral without assigning accounts from another pool or ambiguous repeated swaps. Includes regressions using both reported mainnet transactions and default/zero-copy parser validation.
