Greptile Summary

This PR adds a new "Key concepts" section to docs/concepts/rewrite.md that formally defines Sensitivity and Protection method — two core concepts referenced throughout the rest of the document. The tables satisfy the previous review feedback requesting both discrete sensitivity levels and a structured breakdown of protection method values.

• Sensitivity table introduces the high/medium/low levels with their leakage weights (1.0 / 0.6 / 0.3), which are now properly anchored before their first use in the leakage mass formula later in the doc.
• Protection method table lists all five methods (replace, generalize, suppress_inference, remove, leave_as_is) with descriptions and typical-use guidance, matching the exact enum values used in the codebase.

Confidence Score: 5/5

Documentation-only change with no code modifications; safe to merge.

The change adds a purely descriptive section to an existing doc file. The sensitivity weights and protection method names are consistent with the values already used in the leakage-mass formula and output-columns table elsewhere in the document, and they match the enum values in the codebase.

No files require special attention.
