[candidate-miner] Checkstyle suppresses Target_ClassFinder, a class no longer in the tree

[github-actions]

What is wrong

The Checkstyle suppression file contains a <suppress> entry that targets a
source file named Target_ClassFinder, but no such file exists anywhere in the
repository. The class this line was written to exempt from the
HideUtilityClassConstructor check has been removed, so the suppression now
matches nothing. A maintainer reading the file cannot tell what it protects,
and it will never be exercised by a Checkstyle run.

Where

• File: src/checkstyle/checkstyle-suppressions.xml
• Line (advisory): 46
• Occurrence: <suppress files="Target_ClassFinder" checks="HideUtilityClassConstructor"/>

Evidence

config_kind:             checkstyle_suppression
pattern:                 Target_ClassFinder
raw_line:                <suppress files="Target_ClassFinder" checks="HideUtilityClassConstructor"/>

extractor (miner):       config_dead_entry v1.0.0
score:                   75 (config_kind_prior=40, names_a_literal=25, single_line_fix=10, staleness_years=0)

Suggested fix

Delete the single suppression line for Target_ClassFinder. The file it
referred to no longer exists, so removing the line is the whole change; nothing
else depends on it.

How to verify the fix

From tools/candidate-miner/, run the miner and confirm this fingerprint is no
longer emitted:

./miner.py run --miner config_dead_entry --dry-run
