`claude plugin validate --strict` auto-discovers every .md under a
plugin's agents/ directory as an agent requiring frontmatter, so the
provenance file there always needs fake agent frontmatter to pass
validation. Confirmed empirically that an explicit `agents` manifest
array can't suppress this discovery. Move the file to <plugin-root>/
sources.md instead, and update agent-author/agent-audit accordingly.
Adds ADR-0010, partially superseding ADR-0005's `agents/sources.md`
convention. Fixes#63.

## 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.
