📝 Walkthrough

Walkthrough

This pull request applies formatting and code style improvements across four files in the fbuild project. Function calls, error messages, and test assertions are refactored between single-line and multi-line formats. No logic, control flow, or exported API signatures are altered.

Changes

Cohort / File(s)	Summary
Production Code Formatting crates/fbuild-build/src/esp32/orchestrator.rs, crates/fbuild-cli/src/main.rs	Reformatting of function calls (e.g., materialize_lnk_entry, resolve_root), error messages, and println! statements between single and multi-line styles. No behavioral or semantic changes.
Test Code Formatting crates/fbuild-packages/src/lnk/embed.rs, crates/fbuild-packages/tests/lnk_e2e.rs	Simplification of test assertions and vector initializations; restructuring of test route handler closure. Test behavior and expectations remain unchanged.
