Subject: [PATCH] fix(flows): normalize changed_files to absolute paths for
 incremental flow detection

git diff --name-only returns relative paths (e.g. 'src/main.py') but
the graph stores absolute file_path values (e.g. '/home/user/repo/src/main.py').
The comparison ep.file_path in changed_file_set always failed, causing
incremental_trace_flows to never find new entry points.

Fix: normalize changed_files to absolute paths at the start of
incremental_trace_flows. This fixes both the SQL query (line 473) and
the set comparison (line 513).

Fixes #569
