feat(plugin): package as a Claude Code marketplace plugin
- .claude-plugin/plugin.json v0.1.0 (auto_discover, MIT)
- SessionStart hook: thin zero-dep .mjs wrapper (marketplace convention)
around scripts/coord-inbox.sh, emitting the additionalContext envelope;
always exits 0. Smoke-tested: empty mailbox -> bare continue, pending
message -> injected with UNTRUSTED framing.
- coord-send skill bundled; examples and description use generic repo
names only (coordination metadata never reaches a public surface).
- README (English; documents the deliver-until-done lifecycle correctly,
review §7), CHANGELOG, LICENSE (MIT), CLAUDE.md, package.json +
node --test wrapper around the bash selftest.
