chore(auto-triage): use Claude Max OAuth token and Opus 4.7

Use `claude_code_oauth_token` instead of `anthropic_api_key` so we can
leverage the Claude Max subscription (free under the OSS program) rather
than paying per-token. Also switch the model to Opus 4.7, which is
recommended for agentic coding and is available on Max.

Generate the token locally with `claude setup-token`, then store as
CLAUDE_CODE_OAUTH_TOKEN in GitHub repo secrets.

 ## Setup

+### 1. Add the `CLAUDE_CODE_OAUTH_TOKEN` secret
+
+Uses Claude Max (free for the maintainer via Anthropic's OSS program) instead
+of a pay-per-use API key. Generate a long-lived OAuth token locally:
 
 ```bash
-gh secret set ANTHROPIC_API_KEY --repo nativewind/react-native-css --body "sk-ant-..."
+claude setup-token
 ```
 
+Then add it as a repo secret:
+
+```bash
+gh secret set CLAUDE_CODE_OAUTH_TOKEN --repo nativewind/react-native-css
+# paste the token when prompted
+```
+
+If the OSS Max subscription ever goes away, swap `claude_code_oauth_token` for
+`anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}` in the workflow and
+provide an API key instead.

 ### 2. Verify required labels exist
 
 The workflow applies these labels. Confirm they exist:

 ## Cost
 
-Each Tier 1 run:
+Free under Claude Max (OSS program). Each run uses Opus 4.7 via OAuth.
+
+Rate limits: Max has 5-hour session caps. If the triage workflow runs too
+frequently and hits a cap, subsequent runs will fail until the window resets.
+This is unlikely to be a problem given issue volume, but watch for it.
 
-- Sonnet 4.6 at $3/M input, $15/M output
-- ~5-15 min of runtime on a free GitHub runner
-- Estimated ~$0.20-1.00 per issue depending on complexity
+If switched to API billing: Opus 4.7 is $5/M input, $25/M output. Estimate
+~$1-5 per issue.
