Summary
Adds the Claude 5.5 generation to the model registry:
claude-opus-5.5,claude-sonnet-5.5(plus the-1malias) andclaude-haiku-5.5.-thinkingvariantlow–maxincl.xhigh-1m)low–maxincl.xhighChanges
src/constants.ts: map theclaude-{opus,sonnet,haiku}-5-5[-thinking]andclaude-sonnet-5-5-1m[-thinking]slugs to their Kiro model IDs.src/plugin/model-registry.ts: add specs for the three models. Opus and Sonnet 5.5 are multimodal with thinking, so they get a-thinkingcompanion carrying the reasoning flags. Haiku 5.5 uses the same text+image modalities as Haiku 4.5 but has a 1M context window instead of 200K.src/plugin/effort.ts: addclaude-opus-5.5,claude-sonnet-5.5andclaude-sonnet-5.5-1mtoXHIGH_CAPABLE_MODELS, so their thinking variants get the five-level effort ladder.README.md: list opus-5.5 and sonnet-5.5 among thexhigh-capable models.Tests
effort.test.ts:supportsEffort/supportsXHighEffortfor the new models; Haiku 5.5 reports no effort support.model-registry.test.ts: the new-thinkingentries appear in the thinking andxhighsets; 1M limits; Haiku 5.5 has no-thinkingentry.model-resolution.test.ts: every new slug resolves to the right Kiro model ID.
