chore(lsp): bump iii-sdk to 0.20.0

[guibeira]

Bump iii-sdk to 0.20.0 per https://iii.dev/docs/upgrading/from-0-19-x.md. Build, fmt, clippy, tests green (63 tests). lsp is a stdio language server (no registered surface, interface_smoke:false) so no parity diff applies. No iii-helpers needed.

Poem

🐇 I hopped to the newer SDK gate,
With IIIClient I chatter, light and great.
The engine hums clear,
And errors stay near,
While carrots and code both feel first-rate.
