Add structural CLVM debug metadata and stack symbolization

[bramcohen]

Summary

• emit versioned .debug.clvm.bin sidecars containing deduplicated source files, source text, spans, structural shadow trees, formal parameters, and inferred constraints
• symbolize exact, nested, recursively-curried, and unknown serialized evaluator frames across a collection of sidecars
• decode proper and improper captured environments, preserve rest tails, handle compiler left_env, and unwrap nested @ capture aliases before parameter binding
• render oldest-to-newest captured stacks with bound/runtime parameter values and omitted-frame markers
• expose metadata compilation, decoding, verification, and typed stack rendering through Rust, Python, WASM, and CLI APIs
• index structural identities once so consumers do not scan every metadata tree per frame

The sidecar stores structure rather than persisted tree hashes. Host applications retain control of capture policy, frame serialization, registry limits, lazy loading, and original EvalErr presentation.

Dependencies

Depends on clvm_rs #845. Because downstream chia-gaming currently uses the Chia 0.38 dependency family, this PR temporarily pins the equivalent tested clvmr 0.17.7 integration backport while retaining the version requirement needed for package verification.

The Chia Gaming integration workflow is pinned to the captured-frame implementation from chia-gaming #437 and runs that repository's authoritative Chialisp build rather than maintaining a duplicate build helper.

Verification

• cargo +1.97.1 clippy --workspace -- -D warnings
• cargo +1.97.1 check
• cargo +1.97.1 check --manifest-path wasm/Cargo.toml
• cargo +1.97.1 test — 732 passed, 1 ignored after the nested-capture regression
• cargo publish --dry-run
• all PR checks pass, including crate packaging, NPM, exhaustive tests, all wheel targets, coverage, and the full chia-gaming integration
