v0.5

Added

• ZstdCompressCtx.reset(ZstdResetDirective) / ZstdDecompressCtx.reset(...) —
  recycle a context's native state between frames without freeing and recreating
  it. SESSION_ONLY keeps the level, parameters, and dictionary; PARAMETERS /
  SESSION_AND_PARAMETERS restore the defaults. Binds ZSTD_CCtx_reset /
  ZSTD_DCtx_reset.

• ZstdCompressCtx.loadDictionary(...) / ZstdDecompressCtx.loadDictionary(...)
  (a ZstdDictionary or a native MemorySegment) and refDictionary(...) (a
  pre-digested ZstdCompressDict / ZstdDecompressDict, attached by reference,
  no copy). A sticky dictionary on the context lets compression combine a
  dictionary with the advanced parameters (checksum, window log, long-distance
  matching) — impossible through the per-call compress(src, dict) overloads,
  which route the legacy dictionary path. A parameter reset(...) clears it.
  Binds ZSTD_CCtx_loadDictionary / ZSTD_DCtx_loadDictionary (now on contexts,
  not just streams), ZSTD_CCtx_refCDict, ZSTD_DCtx_refDDict.

Changed

• NativeLibrary.classifier() now throws a clear UnsatisfiedLinkError naming
  the unsupported CPU arch instead of silently mapping it to x86_64 (which
  deferred failure to a cryptic dlopen error). Added an explicit amd64
  branch so Linux JVMs (which report os.arch=amd64) still resolve x86_64.

Fixed

• Native JARs are much smaller. The ELF shared library is now stripped at link
  time (-s), dropping debug info (libzstd.so 4.0M -> ~650K), and the
  multi-MB .pdb debug database and .lib import library that lld emits next
  to the Windows .dll are no longer bundled (neither is needed at runtime).
  Net: linux-x86_64 native jar 1.2M -> 285K, windows-x86_64 1.2M -> 372K.
