Add ctx.register_skill() API so plugins can ship SKILL.md files under a 'plugin:skill' namespace, preventing name collisions with built-in Hermes skills. skill_view() detects the ':' separator and routes to the plugin registry while bare names continue through the existing flat-tree scan unchanged. Key additions: - agent/skill_utils: parse_qualified_name(), is_valid_namespace() - hermes_cli/plugins: PluginContext.register_skill(), PluginManager skill registry (find/list/remove) - tools/skills_tool: qualified name dispatch in skill_view(), _serve_plugin_skill() with full guards (disabled, platform, injection scan), bundle context banner with sibling listing, stale registry self-heal - Hoisted _INJECTION_PATTERNS to module level (dedup) - Updated skill_view schema description Based on PR #9334 by N0nb0at. Lean P1 salvage — omits autogen shim (P2) for a simpler first merge. Closes #8422
