fix(skills): apply the line-anchored delimiter scan to hermes and kimi (#3739)

Hermes overrides SkillsIntegration.setup() with its own copy of the
frontmatter parse and body strip, and Kimi's _is_speckit_generated_skill()
parses frontmatter independently, so all three carried the same
split("---", 2) bug the base class just fixed. A description such as
"Separate sections with --- markers" truncates the parsed frontmatter at the
embedded marker, dropping later keys and spilling the remainder into the
body; for Kimi that means a Speckit-generated skill is no longer recognized
on teardown and gets left behind.

Scan for a closing "---" on its own line instead. The body slice keeps
whatever trails the marker so output stays byte-for-byte identical for
well-formed templates.
