feat(plh): flag plugin.json paths that shadow default folders (CA-PLH-015)

PLH now flags a plugin.json component-path key (commands/agents/outputStyles)
that replaces a default folder still present on disk — Claude Code stops
scanning that folder, so its contents are silently ignored (dead config).
Mirrors CC's /doctor & `claude plugin list` warning (v2.1.140+).

Field set pinned to the docs' "replaces" category only (Verifiseringsplikt,
code.claude.com/docs path-behavior-rules): skills is excluded (adds to the
default skills/ scan — both load) as are hooks/mcpServers/lspServers (own
merge rules); a custom path that addresses the default folder is not flagged.

Tests +5 (936->941). Scanner count unchanged (13). --json/--raw byte-stable.
