Summary

• move the generic Result<T> helpers to @maka/core/result, keep @maka/core/settings/result as a compatibility re-export, and migrate all current production consumers
• reuse stableHash and stableStringify from request-shape.ts in semantic-compact.ts
• preserve the existing raw-hex semantic compact IDs and digests, with focused tests covering the hash output and legacy Result entry point

This is the core + runtime mechanical batch from #1084. It is behavior- and visually-neutral.

Refs #1084.

Verification

• npm run lint — passed
• npm run format:check — passed
• npm run build — passed
• npm run typecheck — passed
• npm --workspace @maka/core test — 1,157 passed, 0 failed
• npm --workspace @maka/runtime test — 2,376 passed, 0 failed, 3 skipped
• git diff origin/main...HEAD --check — passed

Visual validation is not applicable because this is a behavior- and visually-neutral utility cleanup.

Review focus

• stableHash includes a sha256: prefix, while the persisted semantic compact fields currently use raw hex; the small stableHashHex adapter intentionally preserves that existing format
• the old settings Result subpath stays exported and re-exports the same function identities, so existing external imports remain compatible

This looks good. Result now has one implementation at @maka/core/result, while the old settings path re-exports the same function identities for compatibility. Semantic compact reuses the shared hashing code, and the small adapter preserves the existing raw-hex storage format. I also verified that the digest fixture matches the previous implementation. No findings.

A rebase is needed before merging. @me2seeks Would you have a look?
