Pull request overview

This PR removes BLS12-381 from the repo’s public specification/docs and strips BLS-related test scaffolding/step definitions across Rust/Go/.NET test suites, aligning the specs with the stated goal that BLS is not used for transaction signing.

Changes:

• Removed the BLS12-381 section and references from the cryptography specification and related documentation/indexes.
• Removed BLS12-381 state/logic from Rust cucumber test world + steps.
• Deleted BLS-related pending step definitions from Go and .NET test suites and updated status/feature documentation to no longer advertise BLS.

PR description says BLS is being removed from the specification and related documentation, but there are still multiple repo docs referring to BLS/BLS12381 (e.g., AUDIT_REPORT.md, MOCKED_TESTS_REPORT.md, tests//SDK_STATUS.md, tests//PLAN.md). This leaves the documentation set inconsistent after the spec change. Either update those remaining docs to remove/clarify BLS references, or narrow the PR description/scope to match what’s actually being updated here.

This updated priority breakdown removes BLS from Optional, but the summary above still reports Optional as "~110/250" and Total as "578/739". Please recompute and update those scenario totals to reflect the BLS spec/scenario removal so the plan stays internally consistent.
