Add /query command and skill for querying Logfire data

[hramezani]

Summary

• Adds /query slash command for interactive and programmatic Logfire data querying
• Adds query skill (SKILL.md) with schema reference, SQL patterns, MCP and REST API approaches
• Adds full schema reference for records and metrics tables with all columns and types
• Adds client usage reference with examples for Python sync/async clients, DB API 2.0, pandas, and direct REST API (curl, httpx, fetch)
• Mirrors all skill files to skills/logfire-query/ for standalone use
• Updates check-skill-sync.sh with the 3 new file pairs

New files

File	Purpose
plugins/logfire/commands/query.md	/query command workflow
plugins/logfire/skills/query/SKILL.md	Query skill with schema + SQL patterns
plugins/logfire/skills/query/references/schema.md	Full records + metrics table schema
plugins/logfire/skills/query/references/client-usage.md	Python clients, DB API, REST examples
skills/logfire-query/	Standalone mirrors of the above 3

Test plan

• Run bash scripts/check-skill-sync.sh — all pairs in sync
• claude --plugin-dir ./plugins/logfire then /query loads correctly
• Verify skill triggers on "query logfire", "search traces", "find logs"

@hramezani Do you still want to merge this?

Not sure, I created the pr when you asked for it in slack.
We can close it if you think this is not useful
