Michael Jordan 186cad02f9 feat(agent): per-turn micro-compaction to amortize context compression 
Batch compaction pauses a session for one large summarization once the
window fills. Micro-compaction spreads that cost out: after each completed
turn, `finalize_turn` folds the single oldest un-absorbed exchange
(assistant message plus its tool results) into a rolling summary, so the
work happens in small increments during post-turn idle time instead of one
long stall.

Mechanics:
  - a cursor tracks the first message not yet absorbed, recovered from the
    transcript's last summary marker when in-memory state is unavailable;
  - protected head and tail windows are never touched, so the system prompt
    and recent turns stay verbatim;
  - the absorbed span is replaced by a marker carrying the usual
    `_compressed_summary` metadata, so resume, handoff and `/compress`
    treat it exactly like a batch summary;
  - `archive_and_compact` keeps the session DB in step, otherwise the
    append-only flush would leave the original rows active and a resume
    would double-load both summary and originals;
  - when the rolling summary itself passes a token threshold it is
    defragged: re-summarized in one shot and the cursor jumps to the tail;
  - an exchange the summarizer can't handle is retried a bounded number of
    times, then skipped, so one poison exchange can't stall every turn.

Keep only the newest summary marker. The rolling summary is cumulative, so
each marker already contains everything the previous ones held; leaving them
stacked near-duplicate copies of the same text, each with its own heading and
end-marker scaffolding, and the transcript grew on every turn instead of
shrinking. Measured over six turns on a 12-exchange conversation with tool
output: 4104 -> 4797 tokens before, 4104 -> 2572 after.

Off switch: `compression.micro_compact: false` (default on).
