feat: expose package manager name in componentAnalysis result (#518)

* feat: expose package manager name in componentAnalysis result

Attach the matched provider's command name (e.g. pip, uv, poetry) as
`packageManager` on the component analysis result so IDE consumers can
display provider-specific instructions without re-implementing detection.

* refactor: add packageManagerName as public API for all providers

Keep _cmdName as the internal/protected method for binary resolution
and add packageManagerName() as the proper public method on every
provider. This ensures result.packageManager is always set for all
providers, not just when _cmdName happens to exist.
