Summary

Parse a single string directly and allocate a collection only for implicit string concatenation.
Paired profiles save 1–2.4 MB on smaller projects, with estimated savings of 15–46 MB on Sphinx and Prefect and neutral timing.

Test Plan

Testing: Passed the parser test suite, workspace Clippy, hooks, and multi-project output and timing checks.
