Stack 1/3 — E1 proof replay capsule

Base: merged #1690 (main). Stage: C1 / D-RFT-2 / E1, lab-only.

Adds egglog-r2il-probe::artifact::ReplayCapsule over #1690's existing compiled E1 mathematics. Retains exact premises, checked egglog extraction/proof rendering, and executable R2IL scalar steps.

• Cold certify requires complete saturation, a closed term, a checked equality (via the existing egglog public prove command), and a successful R2IL lowering.
• Cold recheck regenerates the proof and compares the complete extracted term, rendered proof and program to the retained capsule. Conservative E1 replay check; not a standalone proof verifier or cryptographic artifact.
• execute reuses the saved R2IL steps without calling egglog. replay rechecks before execution and compares to the independent i128 oracle.
• Tests for E1 parity, rejected missing premise, forged extracted term/proof/program, and overflow.

Not included: durable serialized proof format, 27-atom language, new law admissions, physical-register binding/ABI, production JIT, source writes or changes to contract/R2IL/mask-risc/Thought-Git. No duplicate executor.

Verification: tests authored, not locally executed (this assistant runtime has no Rust toolchain/checkout). CI and code review required. Do not merge autonomously.

Review commands: cd crates/egglog-r2il-probe && cargo test; cargo fmt --check; cargo clippy --all-targets -- -D warnings.

Next stacked PR: certified in-memory catalogue and guarded trusted-baseline fallback (base this branch). EXO-50 ownership claim posted.
