[SC-71] contrib's coverage floor (35%) lags far behind the other three enforced crates

[yusuftomilola]

Overview

contracts/scripts/check-coverage.sh sets per-crate floors of assetsup: 70, contrib: 35, multisig-wallet: 90, asset-maintenance: 70 — contrib sits meaningfully lower than every other enforced crate. Once [SC-57] resolves the uncompiled-file question (which changes what "100% of contrib" even means) and [SC-70] adds insurance/lease coverage, the crate's real coverage should be re-measured and the floor ratcheted up to be in line with its siblings, per the script's own stated policy ("Ratchet these upward as coverage improves; never lower one without saying why").

Tasks

• After [SC-57] and [SC-70] land, re-run cargo llvm-cov for contrib and raise crate_floor()'s contrib case to just below the newly-measured value, matching the pattern used for the other three crates.
• Update the "Measured at time of writing" comment block with the new number.

Acceptance Criteria

• contrib's coverage floor is back in line with the workspace's other enforced crates, with an accurate "measured at" comment.

Dependencies

Depends on [SC-57] and [SC-70].

Notes for Contributors

Requires Rust + Soroban. Workspace: contracts/ (soroban-sdk 23, members: assetsup, contrib, multisig-wallet, multisig-transfer, asset-maintenance). Run cargo test --all, cargo fmt --all -- --check, and cargo clippy --all-targets --all-features -- -D warnings before opening a PR — CI enforces all three. Comment below to be assigned.
