fix(cli): detect docker on Windows PATH (CLEAN-41)

[maksymhryzodub-prog]

Summary

• ranch dev treated Docker as missing on Windows because the CLI looked for binaries with command -v, which Node runs through cmd.exe.
• Shared hasBinary now walks PATH (plus PATHEXT on Windows) and is used for docker, k3d, and kubectl.
• Bump @cleanslice/ranch to 0.1.11 so the fix publishes after merge.

Test plan

• cd cli && bun test src/utils/bin.test.ts
• ensureDockerRunning() succeeds on Windows with Docker Desktop open
• ranch dev gets past the Docker check on Windows (use local CLI or 0.1.11 after publish)

Fixes CLEAN-41
