apm becomes the only supported install path. The flat mirror at each plugin root existed solely so Claude Code's native `claude plugin install` could convention-scan plugin content (ADR-0017). With no native consumers, it cost ~20,000 tracked lines plus ~2,100 lines of sync tooling and ~88s of every push to guard content apm never reads — and its only automated gate, `claude plugin validate --strict`, passes on a plugin with zero content, so it could not detect the defect ADR-0017 was created to fix. Removes the mirror (213 files), the six per-plugin manifest pairs, sync-plugin-content.sh, its 1,289-line test, the orphaned marketplace-plugins.sh, and the check-plugin-content-sync and validate-plugins pre-push hooks. The root `marketplace:` block and .claude-plugin/ catalogue stay: apm's own marketplace consumers read that same file, so `<name>@holocron` short names keep working. tests/run-bats.sh now excludes .claude/skills/. apm installs from .apm/, which carries the tests/ dirs the mirror stripped, so deployed .bats files would otherwise be discovered and double-run.

new-agent.sh
Scaffolds agent definition file(s) from a single root directory input.
Usage: new-agent.sh <agent-name> <root>
Resolves scope by walking up from <root>: a type:-bearing apm.yml found at or above <root> → plugin/APM scope (single file at <package-root>/.apm/agents/<name>.agent.md; an apm.yml without type: is a marketplace-only manifest and is skipped); <root> exactly ~ → user scope (~/.claude/agents/ + ~/.copilot/agents/); otherwise project scope (<root>/.claude/agents/ + <root>/.github/agents/). Each file is a no-op if it already exists. See --help for full usage.
Tests: tests/new-agent.bats (requires bats-support and bats-assert).
