Re: [PATCH v3 0/8] scalar: enable built-in FSMonitor

> This series enables the built-in FSMonitor [1] on 'scalar'-registered

>  * Updated prerequisites for FSMonitor in Scalar to include
>    'fsm_settings__get_reason(the_repository) == FSMONITOR_REASON_OK' to
>    handle cases where the platform is supported, but the repository is not.
>  * Gated enabling the 'core.fsmonitor' on FSMonitor compatibility with the
>    repo.
>  * Replaced 'die()' failures in 'delete_enlistment()' with 'error()'s.
>  * Replaced 'BUILTIN_FSMONITOR' test prerequisite with already-existing
>    'FSMONITOR_DAEMON' for FSMonitor.
>  * Rewrote Scalar enlistment/repo search in 'setup_enlistment_directory()'
>    to avoid unconstrained search and respect 'GIT_CEILING_DIRECTORIES'.
>    Added tests to show the new expected behavior.
