v0.6.0

Minor Changes

• 7dc4790: Restore the ergonomic prepare() and remove retry().

  Reverts the prepare/retry split from the previous release. prepare() once again recovers from error state — it tears down the failed instance, re-initializes from the current options, and warms up — so a single method drives the model to ready from any state. The separate retry() introduced last release is removed; call prepare() to recover instead.

  The MissingUserActivationError message is also sharpened: it now frames a click/keypress as examples of a transient user activation (not the rule), says to call prepare() or the action directly inside such a handler, and names the real traps — effects, timers, page load, and post-await activation expiry.
