fix(kyberforge): address independent review of #154

Quote the template description so the raw scaffold is valid YAML, reject
newline-containing names in new-instructions.sh, correct the empty-compile
facts (exit 1, --clean exits 0), and finish removing commit steps from the
skill-author, agent-author and forge references. Adds regression tests.

 For claude, cursor, windsurf, kiro and antigravity, an existing file at the deployed path is replaced without warning. Copilot skips it and asks for `--force`.

-Plain `apm compile` and `--target all` in a project with no instruction primitives print "no source primitives remain" and exit 0. The apm-workflow compile reference currently says this hard-fails with exit 1 and "No instruction files found in .apm/ directory"; that does not hold in 0.28.0 (see contradictions).
+In a package with no instruction primitives, plain `apm compile --target claude` prints "No instruction files found in .apm/ directory" and exits 1; `apm compile --clean` exits 0. This matches the apm-workflow compile reference. Exit 0 with no output is a different case: instructions exist but are already deployed natively (above).
