Added Enriched --help output (#75)

Closes #74

Added the key scan/watch options (`--ai`, `--severity`, `--format`,
`--config`, `--output`, `--url`, `--supply-chain`, `--stats`, `--debug`,
`--wizard`) directly to the root CLI group so they appear under Options:
in the top-level help output.

Values set at the group level are propagated to `scan` and `watch` as
defaults via `ctx.default_map`, so both invocation styles work
identically:

  pyspector --ai scan path/
  pyspector scan --ai path/   # unchanged, still works
