 cfc165ce6a MUL-8095: fix(execenv): normalize required metadata for Codex user skills (#9346) 
* fix(execenv): normalize required metadata for Codex user skills

Co-authored-by: multica-agent <[email protected]>

* fix(execenv): preserve user skill frontmatter formatting when filling metadata

Inject missing name/description lines instead of re-marshalling the map, so
comments, key order and CRLF endings survive; present-but-empty values are
replaced on the yaml.Node tree. Fix stale expected values in test messages.

MUL-8095

Co-authored-by: multica-agent <[email protected]>

* fix(execenv): only repair what Codex rejects and verify every repair

Codex falls back to the directory name for a missing/blank name and only
requires a non-empty description, so stop injecting name. The one-line
insert is kept for plain block mappings but now re-parsed; flow, indented
and other mappings go through the node rewrite, which expands aliases of a
replaced anchored value and keeps its comments. Every repair must parse and
leave all other fields equal, otherwise the skill is skipped.
