Pull request overview

Adds a GitHub Copilot CLI plugin variant of the existing Connector SDK agent tooling, and wires it into the repo’s plugin-sync and documentation so the same canonical workflows/skills/tools can be used from Copilot CLI.

Changes:

• Extend scripts/sync-plugins.sh to generate/sync a copilot/ plugin directory alongside existing agent targets.
• Add the Copilot CLI plugin tree (copilot/) including agents, skills, commands, hooks, and secure config tooling.
• Update top-level README and add Copilot marketplace metadata under .github/plugin/.

• The usage table omits /fivetran-connector-sdk:evaluate-connector, even though the plugin exposes it for Claude/Gemini/Copilot (and it’s listed elsewhere in this repo). Adding it here makes the install/usage docs consistent.

| Command (Claude Code / Gemini CLI / Copilot CLI) | Codex CLI | Purpose |
|---|---|---|
| `/fivetran-connector-sdk:build-connector` | `$build_connector` | Research an API and generate a new connector |
| `/fivetran-connector-sdk:test-connector` | `$test_connector` | Run and validate an existing connector locally |
| `/fivetran-connector-sdk:deploy-connector` | `$deploy_connector` | Deploy a connector to your Fivetran account |
