Deep Agents Code now emits a `DEBUG` log when a higher-precedence skill
overrides another skill with the same name, aiding skill-resolution
debugging.
---
Skill sources (built-in, plugin, global, project) are merged by
precedence and a higher-precedence skill silently replaces a
lower-precedence one with the same name. This override is intentional
and unchanged; this PR makes it diagnosable by routing both
skill-discovery merge points — the CLI `skills list` loader
(`skills/load.py`) and the runtime `PluginSkillsMiddleware` — through a
shared `merge_skill` helper that emits a `DEBUG` log on each effective
replacement, recording the skill name plus the previous and replacement
source paths and labels.
