Remove jq filter support from MCP server tools

[Copilot]

The jq parameter was available on all MCP server tools (status, compile, logs, audit) to filter JSON output. This parameter is no longer needed.

Changes

Removed JqFilter parameter from all tools:

• statusArgs, compileArgs, logsArgs, auditArgs - removed JqFilter field
• Removed ApplyJqFilter() calls from tool handlers
• Updated tool descriptions to remove jq parameter documentation

Deleted jq infrastructure:

• pkg/cli/jq.go - ApplyJqFilter() function and logger
• pkg/cli/jq_test.go, pkg/cli/jq_integration_test.go, pkg/cli/audit_jq_test.go
• Removed jq-specific test cases from MCP server tests

Updated logs guardrail:

• Removed SuggestedJqQuery type and getSuggestedJqQueries() function
• Guardrail now suggests using max_tokens parameter and native filters (workflow_name, start_date, count) instead of jq

Example

Before:

{
  "name": "status",
  "arguments": {
    "pattern": "*.md",
    "jq": ".[].workflow"
  }
}

After:

{
  "name": "status", 
  "arguments": {
    "pattern": "*.md"
  }
}

Users should use native filtering parameters or adjust output size limits rather than post-processing with jq.

Original prompt

Remove all jq arguments in mcp-server and all jq support in the mcp-server command. The jq variable is not needed anymore.
