Sydney RunkleandClaude Sonnet 4.6 3ef54c1ec8 fix(add_messages): guard fast path against None IDs and intra-right duplicates

Two bugs in the fast-path optimisation:

1. The left-side type guard checked isinstance(BaseMessage) but not
   id is not None. Messages without IDs (e.g. HumanMessage(content="hi"))
   would skip ID assignment and return None IDs.

2. The pure-append short-circuit only checked for overlaps between
   right and left, not duplicates within right itself. A right list
   containing two messages with the same ID would bypass the slow-path
   deduplication and return both.

Fixes:
- Add left_seq[0].id is not None to the type-guard condition.
- Replace the any() overlap check with a set-intersection check that
  also verifies len(right_id_set) == len(right_msgs) (no intra-right
  duplicates) before taking the fast return.
