Conversation
Add ai_generated_lines_added and ai_generated_lines_removed to the code changes of the AI coding session evidence. They hold the lines that all the agent edits of the session added and removed, also the lines that never reached a commit (spec issue-3639, R-011, D-011).

Also note that the session line totals are raw diff totals when a commit cannot be read. Assisted-by: Claude Code Signed-off-by: Jose I. Paris <jiparis@chainloop.dev> Chainloop-Trace-Sessions: d13fc871-d294-4c08-b1d4-e7bdcaef6969

Chainloop Trace now reports, in the AI coding session evidence, the total lines that the agent edits of a session added and removed. The totals include the lines that never reached a commit. Two new fields in
code_changeshold them:ai_generated_lines_addedandai_generated_lines_removed. Compare them withai_lines_addedandai_lines_removedto see how much of the generated code the session kept.The CLI already keeps these counts in the trace state (spec issue-3639, R-011). This PR does the follow-up that D-011 and the Non-goal of the spec defer: it reports the totals in the evidence. The change is additive, and a platform that does not know the fields keeps working (R-009). A session with no commit still sends no evidence, so it reports no totals.
This prepares the "Generated" stage of the AI code lifecycle view (PFM-7302).
