Changelog

v1.0.1

Bump package version to 1.0.1 and raise minimum Rust toolchain to 1.93.0 while updating AWS/chrono/tokio dependencies and the bundled build.sh base image so the build stays aligned with the updated ecosystem.
Harden CodeCommit signing by sorting/enumerating regions, adding the eusc-de-east-1 sovereign endpoint, and refactoring signature generation to reuse fixed-size buffers and binary search for region lookup; this eliminates heap churn, trims string allocations, and keeps the canonical request consistent.
Simplify profile parsing and URL handling so the helper reads credentials straight from the user-info payload without extra allocations or fallback heuristics.
