Add .gitignore; fix move command syntax (name= → to=)

- Add .gitignore to exclude test-results/ from version control
- Fix `obsidian move` syntax in SKILL.md and command-reference.md:
  the parameter is `to=<full-path>` not `name=<filename>` (confirmed
  by live testing against TestVault — CLI exits 0 with error message
  when name= is used, silent failure)
