ci: add Claude issue triage workflow for bug reports (#1011)

## Summary
- Adds a GitHub Actions workflow that triggers Claude Code to analyze
newly opened bug issues
- Security hardened: no user-controlled string interpolation in prompts,
shallow clone, no persisted credentials, read-only tool permissions
- Only triggers on this repo (not forks), on issue creation, and only
for issues labeled `bug`

+
+            1. Search the codebase to gather relevant context (related files, existing implementations, tests)
+            2. Determine if the issue is fixable and estimate the complexity
+
+            Post a comment on the issue with:
+            - A brief summary of your understanding of the issue
+            - Relevant files/code you found
+            - Whether this issue is fixable (yes/no/needs clarification)
+            - If the issue is unclear, ask for more context
+            - If fixable, provide a concrete implementation plan with specific steps
+            - Any potential concerns or blockers
