fix: Classify Capped Artifact Probe Candidates

[danny-avila]

I fixed the output-cap probe so artifacts that are ineligible for collection retain their normal truncation classification instead of being mislabeled as max-files omissions. This closes #205.

• Validate supported artifact paths before treating them as hidden by the output-file cap.
• Stat cap-probe candidates and classify oversized files as size truncations.
• Preserve bounded hashing and unchanged inline-entrypoint/session suppression behavior.
• Add regression coverage for oversized and overlong supported files after the output cap is full.

Change Type

• Bug fix (non-breaking change which fixes an issue)

Testing

• Ran the focused walker suite: 59 passed.
• Ran the complete API suite with the host-only AWS_CA_BUNDLE variable removed: 434 passed, 16 skipped, 0 failed.
• Ran git diff --check.
