Add --verbose flag to doctor check command

[Copilot]

Users on large WordPress sites (30k+ posts, 200k+ comments) reported wp doctor check --all appearing to hang at 12% with no indication of progress or what check was executing.

Changes

• Added --verbose flag to display check execution progress:

  • Check name before execution: Running check: {name}
  • Status after completion: Status: {status}
  • File scan progress every 1000 files: Scanned {count} files...
  • Total files scanned: Total files scanned: {count}

• Disabled progress bar when verbose active - the two modes interfere visually

• Added VERBOSE_FILE_SCAN_INTERVAL constant for scan progress interval (1000 files)

Example Output

$ wp doctor check --all --verbose
Running check: autoload-options-size
  Status: success
Running check: core-update
  Status: success
Scanning filesystem for file checks...
  Scanned 1000 files...
  Scanned 2000 files...
  ...
  Scanned 12000 files...
  Total files scanned: 12543
Running check: php-in-upload
  Status: warning

Default behavior unchanged - verbose mode is opt-in.

<issue_title>Introduce --verbose flag to provide more visibility into what checks are doing</issue_title>
<issue_description>Run wp doctor check command as follows:
[root@server production]# wp doctor check --all --allow-root

Check begins but never gets past 12%

Running checks 12 % [====================> ] 0:16 / 2:15[root@server production]#

Expected behavior is that it completes or returns an error message.

Ideally a fix would complete the scan, alternatively provide a verbose error message.

Thanks!

@danielbachhuber Thanks for the report, @bozzmedia !

I imagine it's processing a large body of data (files or in your database) for a specific check, and is slow to update the progress indicator.

It would be nice to have a --verbose flag that gives you more visibility into what each check is doing.</comment_new>
