gem-team: Add tracing to browser-tester, and improve agent docs and constraints (#1094)

* <think>The user wants me to generate a conventional format commit message based on the git diff output provided.

Let me analyze the changes:

1. **`.github/plugin/marketplace.json`**:
   - Updated the "gem-team" plugin description to include "complexity-aware research, multi-plan selection for critical tasks"
   - Updated version from "1.2.1" to "1.3.0"

2. **`agents/gem-browser-tester.agent.md`**:
   - Added `<tools>` section with new tools: get_errors, mcp_io_github_chr_performance_start_trace, mcp_io_github_chr_performance_analyze_insight
   - Modified the `<expertise>` section (moved closing tag)
   - Updated `<input_format_guide>` to use proper JSON code block format
   - Updated `<output_format_guide>` to add "needs_revision" status option and restructured JSON formatting
   - Updated `<constraints>` section - significantly changed the guidelines

This appears to be an update to:
- Plugin marketplace version bump
- Browser tester agent improvements (new tools, updated workflow constraints, better formatting)

Let me generate a conventional commit message:
- Type: Could be "feat" for new features or "chore" for maintenance
- Scope: could be "marketplace" and "browser-tester"
- Message should describe the changes succinctly

Looking at the changes more carefully:
- Plugin version bump from 1.2.1 to 1.3.0 - this is a feature update
- New tools added to browser tester agent
- Updated constraints/workflow for browser tester

I'll create a commit message that captures the essence:
</think>

feat: update gem-team to v1.3.0 and enhance browser-tester agent

- Bump gem-team plugin version from 1.2.1 to 1.3.0 with updated description
- Add performance tracing and insight tools to browser-tester agent
- Refactor input/output format guides with proper JSON code blocks
- Update agent constraints with improved tool usage and batching guidelines

* fix: correct typo "suiteable" to "suitable" in agent documentation

 - Tool Usage Guidelines:
   - Always activate tools before use
   - Built-in preferred: Use dedicated tools (read_file, create_file, etc.) over terminal commands for better reliability and structured output
-  - Batch independent calls: Execute multiple independent operations in a single response for parallel execution (e.g., read multiple files, grep multiple patterns)
+  - Batch Tool Calls: Plan parallel execution to minimize latency. Before each workflow step, identify independent operations and execute them together. Prioritize I/O-bound calls (reads, searches) for batching.
   - Lightweight validation: Use get_errors for quick feedback after edits; reserve eslint/typecheck for comprehensive analysis
-  - Think-Before-Action: Validate logic and simulate expected outcomes via an internal <thought> block before any tool execution or final response; verify pathing, dependencies, and constraints to ensure "one-shot" success

 - Tool Usage Guidelines:
   - Always activate tools before use
   - Built-in preferred: Use dedicated tools (read_file, create_file, etc.) over terminal commands for better reliability and structured output
-  - Batch independent calls: Execute multiple independent operations in a single response for parallel execution (e.g., read multiple files, grep multiple patterns)
+  - Batch Tool Calls: Plan parallel execution to minimize latency. Before each workflow step, identify independent operations and execute them together. Prioritize I/O-bound calls (reads, searches) for batching.
   - Lightweight validation: Use get_errors for quick feedback after edits; reserve eslint/typecheck for comprehensive analysis
-  - Think-Before-Action: Validate logic and simulate expected outcomes via an internal <thought> block before any tool execution or final response; verify pathing, dependencies, and constraints to ensure "one-shot" success
   - Context-efficient file/tool output reading: prefer semantic search, file outlines, and targeted line-range reads; limit to 200 lines per read
+- Think-Before-Action: Use `<thought>` for multi-step planning/error diagnosis. Omit for routine tasks. Self-correct: "Re-evaluating: [issue]. Revised approach: [plan]". Verify pathing, dependencies, constraints before execution.
 - Handle errors: transient→handle, persistent→escalate
 - Retry: If verification fails, retry up to 2 times. Log each retry: "Retry N/2 for task_id". After max retries, apply mitigation or escalate.
