fix: document Gradle fork build and warn when native library is missing under CodSpeed The README said to build the fork with Maven, which does not bundle the native libraries. The fork then silently ran as plain JMH and produced no results. Document the Gradle build with recursive submodule init, and print a warning when CODSPEED_ENV is set but the native library cannot load.

chore: Release v0.2.1

main

perf(perf-map-agent): index the git root once instead of walking it per source lookup Every distinct class-relative source path that is not on disk (JDK and dependency classes) triggered a full recursive walk of the git root on the JVM service thread, concurrently with the running benchmark. With ~130 distinct misses on a ~6500-file tree this was ~130k getdents64 and ~450k stat calls, and ~1s of service-thread CPU during a ~3.5s run. The git root is now walked exactly once into a basename-keyed hash index; each lookup is a single bucket scan for the suffix match. The walk uses d_type to avoid a stat per entry, falling back to stat only for symlinks and DT_UNKNOWN. Same measurement after the change: 968 getdents64, 7 extra stats, 0.03s service-thread CPU.
