v0.6.0

[0.6.0] - 2026-05-18

Added

• erllama:continue/3 for caller-asserted chat-template continuation
  on a sticky session. Skips the prompt prefix-equality check in
  resolve_sticky_continuation so chat templates whose rendered
  prefix shifts between turns can still reuse the live KV cells.
  Caller passes the tokenised tail directly; the engine prefills
  only that tail on top of the pinned seq's stored KV. Returns
  {error, no_session} for unknown session ids and
  {error, sticky_busy} for in-flight seqs. New
  cache_hit_kind => continuation reports the path in Stats.
  Companion guide section in guides/examples.md and lifecycle
  notes in internals/request-lifecycle.md.
