• File sim/agent_clone_test.go — part of check-in [38efed7a12] at 2026-08-12 20:50:57 on branch main — chore(deps): migrate to go-libfossil v0.9.0 (#195)

  * chore(deps): migrate to go-libfossil v0.9.0 (renamed module path)

  - import path danmestas/libfossil → danmestas/go-libfossil everywhere - CloneOpts.ProjectCode removed upstream; assert via CloneResult instead - Timeline now takes TimelineOpts (cursor pagination, newest-first) - testutil.HasFossil removed; check FossilBinary() != ""

  * ci: retrigger checks
