Improved --Toolchain_resolution_debug’ing
summary
Refactors Bazel’s `--toolchain_resolution_debug` output into a single-message-per-invocation, indented format that removes duplicate lines and makes the two-phase algorithm explicit: phase one assigns toolchains per execution platform in declaration order, phase two picks the execution platform with all required and the most optional toolchains. Demonstrates with multiple execution and target platforms, shows the implementation change that stops early when every execution platform has an assignment and prints one clear recap per query, and reports measurable speed and readability improvements.
