Tianyi Cui 2bae18f811 fix(session): synthesize tool results for interrupted tool calls on crash recovery (review #33) ...

The loop logs the assistant/message (carrying tool-call blocks) BEFORE running
the tools, so a crash mid-tool leaves durable tool calls with no matching
tool/result. interruptedTurnClosers only added step/end + turn/end, so a resumed
session's deriveMessages() replayed a dangling assistant tool-call — which every
provider rejects as an invalid transcript on the next request.

interruptedTurnClosers now scans the interrupted turn for tool-call blocks
without a matching tool/result and synthesizes an error tool/result for each
(before the step/end), so the rehydrated history is a valid transcript. Adds a
dedicated repair.spec.ts and a shared-contract case proving both backends pair
every orphaned call with a result. Docs (ADR 0018, both persistence READMEs,
load() JSDoc) updated.

Also fixes the echo-agent README session-cleanup path: demo:echo runs from the
repo root, so sessions land in <repo-root>/.sessions/_no-cwd/, not
examples/echo-agent/.sessions/ (review #33).
