Greptile Summary

Automated benchmark update for v3.0.0 documenting performance metrics on 164 files (up from 146 in v2.6.0).

• Native full build: 286ms → 721ms (+152%)
• WASM full build: 899ms → 2.0s (+128%)
• Native 1-file rebuild: 135ms → 325ms (+141%)
• Import pairs increased: 171 → 201

The performance regressions are significant and warrant investigation in the codebase, but this PR correctly documents the measured benchmark data. Markdown formatting and JSON data structure are valid.

Confidence Score: 5/5

• Safe to merge - automated documentation update with valid formatting and data
• Documentation-only change from automated workflow; markdown and JSON formatting are correct; data is internally consistent; no code changes introduced
• No files require special attention
