fix: /learn writes to HERMES_HOME/skills instead of ~/.hermes/skills (#65165)

[webtecnica]

/reload-skills was using stale import-time SKILLS_DIR instead of dynamic get_skills_dir(). Changed scan_skill_commands() to use the dynamic resolver.\n\nCloses #65165

Thanks for investigating the HERMES_HOME symptom. This is an automated hermes-sweeper review; current main already provides the requested behavior.

• Commit c6a3d412d (fix(skills): widen call-time skills-dir resolution to skill_manager_tool) is contained in current main and changed skill-manager path resolution to use the live profile-scoped home.
• tools/skill_manager_tool.py:156-168 resolves the active skills root as get_hermes_home() / "skills", and _resolve_skill_dir() uses that helper at tools/skill_manager_tool.py:578-582.
• hermes_constants.py:75-77 gives an explicit HERMES_HOME value precedence, so HERMES_HOME=/opt/data resolves creates under /opt/data/skills.
• The current PR diff only adds a skills.allow_create gate in tools/skill_manager_tool.py; it does not alter the path resolver or scan_skill_commands().

The linked issue #65165 was also closed through PR #65212 with this current-main implementation.
