v0.10.0

Adopted sigil: ^0.14 (sigil-stdlib auto-derived). Rewired sigil-json to its canonical extracted URL at ^0.14.0.

The previous bump attempt on 2026-04-26 was blocked by a runtime 'unbound variable cddddr' error from src/ledger.sgl: the four-level cdr accessor was removed from the prelude in 0.14.x and the comment- referenced (scheme cxr) module had been extracted to a separate sigil-r7rs repo. Resolved by replacing the single call site with list-ref, which reads the same 5th element through prelude-exported R7RS surface. No new dep added.

55/55 tests pass against sigil-lang v0.14.4.
