M5: skills (SKILL.md and skill tool)

Adds harness-core::config::markdown to parse SKILL.md frontmatter/body, a skill tool in harness-tools to invoke them, and system-prompt wiring so available skills are advertised to the model. Includes the rustfmt pass over the M5 files touched by this and the preceding LSP/rmcp work.
