fix(skills): remove broken doc references in orca-cli SKILL.md (#973)

* fix(skills): remove broken doc references in orca-cli SKILL.md

Three files listed under ## References do not exist in the repository:
docs/orca-cli-focused-v1-status.md, docs/orca-cli-v1-spec.md, and
docs/orca-runtime-layer-design.md. Agents following the skill would hit
dead links when trying to resolve ambiguous CLI behavior. Replace the
stale list with a general pointer to the docs/ directory.

 Those were useful while the feature was taking shape, but they were intentionally removed
