fix: address PR review comments for documentation accuracy

- Remove reference to non-existent :FallCustomCheck command
- Fix coordinator list (compact, separate instead of stack)
- Fix theme list (ASCII, DOUBLE, SINGLE instead of MINIMAL)
- Remove "delete" from FallSession description
- Clarify that mappings can be confirmed (not customized) via F1
- Update examples to match actual available components
