Ignore invalid file patterns individually (#64525)

## Objective

Prevent one invalid file pattern from discarding valid patterns or
causing settings loading to panic.

The pre-existing exclusion-matcher bug was reported during review of
#64492 (part of #64399).

## Solution

Ignore invalid entries individually and log their errors in
`file_scan_exclusions`, `file_scan_inclusions`, `file_types`,
`hidden_files`, `private_files`, and `read_only_files`.

Preserve valid inherited entries without changing `"..."`, replacement,
or empty list behavior. Valid brace inclusion patterns remain usable,
including when an alternative spans multiple directories.

## Testing

Reproduced matcher loss and inclusion and file type panic paths before
fixing them. Targeted tests pass on macOS for mixed, inherited,
replacement, empty, and all-invalid lists, including inherited `.git`
exclusions, private file protections, and inclusion rescans with brace
patterns.

Windows and Linux execution remains untested.

Release Notes:

- Fixed invalid file patterns discarding valid exclusions, hidden file
rules, or read-only rules, or causing inclusion settings to panic. Also
fixed invalid private file patterns discarding valid protections and
invalid file type patterns causing settings loading to panic.
