Fully-qualify kickoff's /continue → /work-system:continue

[gering]

Summary

• A Claude Code built-in/alias /continue can shadow the work-system plugin skill, and plugin skills are only guaranteed reachable via their plugin:skill namespace. So a /kickoff-launched Claude worker running the bare /continue in a fresh worktree ran CC's own resume (nothing to resume → idle, TASK.md never loaded) instead of the work-system resume flow — breaking the core kickoff→worker handoff (P1).
• Switch every machine-generated launch invocation to the plugin-qualified /work-system:continue, which resolves unambiguously and can't be shadowed.
• work-system bumped 1.9.1 → 1.9.2 (patch, bugfix).

Changes

• Launch sites (machine-generated):
  • agent-registry.sh emit_argv (the primary selector path) + its argv-shape header comment
  • herdr-launch.sh legacy no-selector fallback + header comment
  • kickoff/SKILL.md outside-herdr manual launch block
  • adopt/SKILL.md outside-herdr manual launch block (same bug, not originally enumerated)
  • README launch examples (root + work-system)
• Tests: test_agent_registry.py asserts the argv ends in /work-system:continue.
• Human-typed reopen prose: continue/SKILL.md description + README reopen section updated to the qualified form (that bare command is what the built-in shadows); casual skill-name mentions left readable.
• Docs: knowledge herdr-kickoff-automation.md gains a dedicated shadowing gotcha (verified CC finding + plugin-cache deployment caveat); CHANGELOG entry added.

Verified CC finding

No documented built-in /continue slash command exists, but per CC's own docs plugin skills are only guaranteed reachable via the plugin:skill namespace — the bare form is not reliable. The exact mechanism (built-in shadow vs. namespace-only resolution) is CC-version-dependent; the fix is orthogonal, since /work-system:continue is the one unshadowable invocation.

Deployment note

agent-registry.sh / herdr-launch.sh run from the plugin cache, not the repo, so live launches only pick up this fix after a /plugin marketplace update + reload refreshes the cache.

Readiness

• ✅ Version synced (plugin.json + marketplace.json → 1.9.2)
• ✅ CHANGELOG entry added
• ✅ Knowledge updated (herdr-kickoff-automation)
• ✅ READMEs updated (root + work-system)
• ✅ Tests: test_agent_registry.py, test_herdr_launch.py pass
• ✅ check-structure.py: 0 errors
• ➖ Build/Lint: N/A (markdown/plugin repo; shell syntax covered by check-structure)

Test plan

• python3 plugins/work-system/scripts/test_agent_registry.py → all pass (asserts qualified argv)
• python3 scripts/check-structure.py → 0 errors
• After cache refresh: /kickoff a Claude worker → the tab runs /work-system:continue and loads TASK.md
