chore: Release v0.2.1

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.

fix(uri): make benchmark source file detection language-agnostic Resolve the source path from the class file's SourceFile attribute first, then fall back to searching known source extensions (java, kt, scala, groovy) instead of hardcoding .java. Kotlin and Scala benchmarks now get the correct file_path in their CodSpeed URI.

fixup! fix(uri): make benchmark source file detection language-agnostic Replace handwritten class-file parsing with an ASM source visitor. Keep resource lookup and missing-metadata fallback unchanged, and align Maven and Gradle on ASM 9.9.1 to read modern benchmark class files.
