v0.11.0 — installable plugin marketplace

Added

• .claude-plugin/marketplace.json — the repo now doubles as its own single-plugin marketplace, so the bundled skills install via Claude Code:

  /plugin marketplace add edwilde/ticketgraph
  /plugin install ticketgraph@ticketgraph
  

  (source: "./", no version — plugin.json stays the single source of truth.)

Changed

• Renamed the outstanding-tickets skill to outstanding so the automatic plugin namespace reads cleanly as /ticketgraph:outstanding rather than the redundant …:outstanding-tickets. Sets the terse-name convention for the planned wrapper family.
• Documented the marketplace install in README + docs/install.md.

Notes

• The marketplace install ships skills only. They drive the ticketgraph CLI, which depends on the native better-sqlite3 addon — a plugin clone does not build it, so the binary still needs a dev build (npm publish is the planned binary-distribution path, not yet done).
