Add append_provisional_record/_drop_provisional_records so an aborted turn is recorded as a tail-only trajectory record without committing token state, superseded by the next committed turn. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Adds the provisional-record mechanism to
LinearTrajectory:append_provisional_record(record)— appends a record as the trajectory tail without committing it to token state (num_assistant/token_idsleft untouched). Used for an aborted generation (finish_reason == "abort", e.g. an SGLang weight-update pause) so the agent's abort-retry re-issues the same turn from the prior checkpoint._drop_provisional_records()— discards any trailing record past the committed count.update_pretokenized_statenow drops provisional records first, so a successful turn supersedes a prior provisional abort andmerge_samplesnever sees a mid-trajectory ABORTED record.If retries are exhausted, the provisional remains as the honest final ABORTED turn.
