## Why
Two issues were found in `validate-provenance.sh` by `/skill-audit`:
1. `find_plugin_root` only walked up looking for bare `plugin.json`, missing
the `.claude-plugin/plugin.json` layout used by kyberforge plugins — matching
the logic already present in `validate.sh`.
2. Check numbers in `--help` and inline comments had a gap (0,1,2,4,5,6) from
a previously removed check, making the numbering confusing to readers.
## Implementation Notes
Check numbers renumbered sequentially 0–5 in both the `--help` output block
and the inline `# --- Check N:` comments. The `find_plugin_root` condition now
mirrors the `detect_scope` function in `validate.sh`.

## Why
agent-author produces agents/sources.md at plugin scope to record which
research sources informed which agent files. agent-audit had no way to
validate this chain, leaving stale or missing provenance undetected.
## Implementation Notes
Validation is per-pair (the given agent file + its counterpart) rather
than plugin-wide, keeping the scope consistent with validate.sh. The
script exits 0 silently for non-plugin-scope agents.
source_keys is top-level in both CC .md and Copilot .agent.md files
(not under metadata:) to avoid conflict with Copilot's own metadata
field semantics. Checks 0, 1, 2, 4, 5, 6 mirror the skill provenance
set; upstream research-doc cross-reference checks (7, 8) are deferred.
agent-author Steps 2, 3, and 4 updated to formally specify the
agents/sources.md format and instruct authors to add source_keys to
both files when research sources are in context.
