chore(coder): bump iii-sdk to 0.20.0

[guibeira]

Bump iii-sdk 0.16.0-next.2 → 0.20.0 per https://iii.dev/docs/upgrading/from-0-19-x.md. IIIError→errors::Error, III→IIIClient, protocol/runtime submodules. Build, fmt, clippy, tests green (324 tests); 10-function surface (coder::*) intact, all schemas typed (--assert-typed-schemas exits 0; on-config-change already typed). No import aliases.

Note: PR #340 proposes merging coder into shell — if that lands, this becomes moot; until then coder is kept current with 0.20.

📝 Walkthrough

Walkthrough

The PR bumps iii-sdk to 0.20.0 and updates coder runtime and tests to use IIIClient plus iii_sdk::errors::Error and protocol-scoped TriggerRequest imports. Configuration registration, function handlers, engine helpers, and integration test types are aligned to the new API.

Changes

iii-sdk 0.20.0 client migration

Layer / File(s)	Summary
Configuration runtime migration coder/Cargo.toml, coder/src/main.rs, coder/src/configuration.rs	iii-sdk is bumped to 0.20.0, and configuration registration, fetch, trigger, and retry code switches to IIIClient and iii_sdk::errors::Error.
Function registration updates coder/src/functions/mod.rs	The function registry and each handler registration use IIIClient, and handler errors map through Error::from; the drift-guard test constructs IIIClient.
Test harness client types coder/tests/common/*, coder/tests/integration.rs	The shared test engine, worker helpers, world state, and integration test call sites switch to IIIClient, Error, and iii_sdk::protocol::TriggerRequest imports.

Poem

🐇 I hopped through the code by moonbeam light,
IIIClient twinkled where III once sat bright.
A carrot of Error now guides the way,
And trigger bells jingle in protocol play.
Thump—thump—this bunny says: “Ship it today!”
