* fix(#1374): surface diagnostic when configured agent skills all fail to resolve

buildAgentSkillsBlock returned '' (only ad-hoc per-path stderr warnings) when an agent configured via agent_skills had paths that all failed to resolve — missing SKILL.md, unsafe path, invalid global name, OR a malformed (non-string/non-array) value. query agent-skills --json reported skills_count>0 with an empty block and no machine-readable signal, so a fully-dropped configuration was indistinguishable from a resolved one.

Thread an optional diagnostics collector through buildAgentSkillsBlock: route every skip warning through a warn() helper (stderr + collector), flag truthy-but-malformed config values, emit an aggregate warning when configured paths resolve to zero skills, and surface the collected reasons in a new warnings[] field on the query agent-skills --json IR. Empty arrays and falsy values stay silent (skills_count is honestly 0). skills_count semantics unchanged. Docs updated for the new IR field.

The `--json` flag returns a typed IR object suitable for structured consumption and test assertions, while the default (no flag) preserves the raw XML output that workflow shell expansions rely on.
The `--json` flag returns a typed IR object suitable for structured consumption and test assertions, while the default (no flag) preserves the raw XML output that workflow shell expansions rely on. The IR also includes a `warnings` array naming any configured skill paths that were skipped (for example a missing `SKILL.md`); it is empty when every configured skill resolved.
