## Title

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

## Body

    ## 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.. Run --model to pick a different model.
    ```

    GitHub anthropics/claude-code-action #1850
