Deploying skills runs Emacs only — run it directly, not C++ compilation

compass build --direct skills only invokes Emacs in batch mode via projects/ores.lisp/src/ores-build-skills.el; it performs no C++ compilation and needs no cmake/vcpkg. Claude can run it directly without asking the user.

Why: Session on 2026-05-22 incorrectly deferred the command to the user by applying build-parallelism concerns (-j $(nproc) crash risk, build wrapper) to a target that does not compile anything. The user corrected this and requested the rule be made explicit.

How to apply: When the user asks to regenerate or redeploy skills, run:

./compass.sh build --direct skills

from the project root. Do not ask the user to run it. --direct calls Emacs directly (no cmake/vcpkg), so it also works in a light environment; the -j caps only apply to C++ compilation targets. The equivalent deploy_skills CMake target works too in a full environment.
