Register Dock's shared Claude Code plugin marketplace

[gasher]

Summary

• Registers docknetwork/dock-claude-skills as a plugin marketplace and enables dock-skills@dock for this repo, so anyone opening it here gets the shared marketplace with no manual install step.
• Adds one boilerplate skill (.claude/skills/example-skill/) as a starting point for this repo's own skills — disabled by default, meant to be copied and rewritten, not used as-is.

This is infrastructure setup for the shared skills effort — the marketplace repo itself is still just a scaffold with no skills in it yet.

Test plan

• Open this repo fresh and confirm the dock marketplace registers and dock-skills installs without prompting for credentials
• Confirm no unrelated .claude/settings.json keys were touched (only extraKnownMarketplaces / enabledPlugins were merged in)
