Add Claude Code marketplace configuration

[hwittenborn]

This allows users to install and update gstack through the native Claude Code plugin system:

/plugin marketplace add garrytan/gstack
/plugin install gstack@gstack-marketplace

• Adds .claude-plugin/ marketplace and plugin manifests
• Moves skills into skills/ directory for plugin auto-discovery
• Uses ${CLAUDE_SKILL_DIR} for portable paths
• Removes (now unneeded) setup script

Pull request overview

Adds Claude Code plugin marketplace support for gstack by introducing .claude-plugin manifests, reorganizing skills for auto-discovery under skills/, and updating the browse CLI/build/test setup to match the new layout.

Changes:

• Add .claude-plugin/plugin.json and .claude-plugin/marketplace.json for marketplace install/update.
• Move skills under skills/ and update skill docs to use ${CLAUDE_SKILL_DIR} for portable paths.
• Remove legacy setup/skill entrypoint files and update Bun build scripts + ignore patterns for the new skills/browse location.

• The build command is run from ${CLAUDE_SKILL_DIR}, but that directory does not contain package.json/dependencies (they live at the repo root). As written, bun install/bun build will fail or install a second, isolated node_modules. Update the instructions to run from the repository root (or invoke bun build with absolute paths while staying in the root) so Playwright/diff dependencies resolve correctly.

Closing — the Claude Code marketplace plugin system isn't something we're adopting. The current setup script + skill symlink approach works and we don't want to restructure the repo layout.

[hwittenborn]

Is the issue with backwards compatibility, or that you just don't want to adopt the marketplace layout in general? I do think a marketplace will help users install much more easily, since that's how users are already updating the rest of their skills/marketplaces/etc.
