Add LiteSVM integration test for cnft-vault withdraw_cnft

Adds programs/cnft-vault/tests/test_vault.rs, a LiteSVM test that:
- loads the built cnft-vault program plus the three mainnet fixtures
  (mpl-bubblegum, spl-account-compression, spl-noop)
- creates a Bubblegum ConcurrentMerkleTree<3,8> and mints a cNFT whose
  leaf_owner is the vault PDA (seeds [b"cNFT-vault"])
- recomputes data_hash/creator_hash, builds the index-0 empty-node proof,
  reads the live root
- calls withdraw_cnft (CPIs Bubblegum Transfer, vault PDA signs via
  invoke_signed) to move the cNFT to a recipient, asserting success and
  that a replay with the now-stale root fails

Also: add #![allow(clippy::diverging_sub_expression)] (accepted Anchor
#[program] false positive) and #[allow(clippy::too_many_arguments)] on
build_transfer_instruction, plus rustfmt cleanup, so fmt/clippy are clean.

withdraw_two_cnfts is left untested (would need two trees/leaves/proofs).
