v0.6.1

[0.6.1] - 2026-05-18

Fixed

• BEAM segfault in erllama:apply_chat_template/2 on rendered
  chat-template output above the initial 4 KiB render buffer. The
  vendored llama_chat_apply_template returns the full formatted
  size as a positive value even when the caller's buffer was too
  small (strncpy silently truncates). The NIF retry path only
  fired on negative return, so the positive size was fed as
  text_len to llama_tokenize and the subsequent std::string
  construction walked past the truncated buffer into unmapped pages.
  Retry now triggers on written > buf_size. Caps bumped to match
  the downstream's 64 MiB body limit: ERLLAMA_MAX_TOKEN_TEXT
  4 MiB → 64 MiB, ERLLAMA_MAX_TOKENS 1 M → 16 M. The token output
  cap is enforced on the tokenize success path so byte-fallback
  tokenizers don't return over-cap lists.
