[claude-code-action] Bedrock: every docs example model ID fails (400 invalid / 404 end-of-life) — use the Claude Opus 5.5 inference profile

## Observed symptom Bedrock: every docs example model ID fails (400 invalid / 404 end-of-life) — use the Claude Opus 5.5 inference profile Thanks for the `[1m]` docs and for surfacing `contextWindow` in the result output (#1608). I used that same field to check the IDs below. `main` at 9ca9355 already runs Claude Opus 5.5 on Bedrock with no action changes. The only problem is the docs examples. ## Literal error text ``` API Error (anthropic.claude-4-0-sonnet-20250805-v1:0): 400 The provided model identifier is invalid..
