fix: bound large tool trace arguments

[chubes4]

Summary

• Keeps bounded, already-redacted tool arguments in traces even when the full argument payload is too large to include.
• Preserves high-signal fields like repo, issue_number, and action while truncating long strings and still marking the full payload as omitted.

Verification

• php tests/tool-trace-metadata-smoke.php

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (openai/gpt-5.5)
• Used for: Diagnosed opaque E2E tool failures, implemented bounded trace argument output, and added smoke coverage; Chris remains responsible for review and merge.
