Note: Per-tool jq response filters already implemented via PR #5273

[Copilot]

Issue #5270 requested per-tool jq response filters to reduce token bloat from large MCP tool responses (e.g., list_code_scanning_alerts where rule.help repeats full CWE docs per alert).

This feature was fully implemented and merged in PR #5273. No additional changes needed — the implementation is already live:

• Config: ToolResponseFilters map[string]string on ServerConfig (TOML + stdin JSON)
• Validation: jq expressions compiled at startup; invalid filters fail fast
• Pipeline: filters applied in jqschema middleware before payload preview/schema generation
• Tests: coverage in jqschema_test.go and config/validation_test.go
