Subject: [PATCH] fix(app): abort session on synthetic continue loop detection
 (#777)

When the LLM outputs "Suggested next steps for continuation" at the end
of a work summary, OpenCode sends a synthetic "continue" prompt which
triggers another summary, creating an infinite loop. The existing
diagnostic code detected this (3+ synthetic continues in 60s) but only
logged a warning.

Now calls session.abort() on first loop detection to break the cycle.
Uses a per-session Set to ensure abort fires only once per session.
