v0.1.3 — Fix Claude Code install bug #56043

Fixed

• Marketplace install bug: top-level name in marketplace.json previously matched the plugin name (context-handoff), triggering Claude Code issue #56043 which misclassifies the install as a "remote plugin with unrecognized source." Renamed the marketplace to se4thvin-plugins.

Changed

• Slash command /recap renamed to /handoff-resume for clarity.

This is the first release that actually installs cleanly on Claude Code.
