Backends create the workspace directory as their first start() step, so checking workspace.exists() after start() always returned True and the bootstrap-copy branch was dead. Snapshot existence before start() so bootstrap files are copied for genuinely new workspaces.

Summary
Sandbox bootstrap files were never copied into a workspace that already existed on disk, so a reused workspace never received its bootstrap content.
Problem
The bootstrap-copy decision was made after
start()had already created the workspace directory, so the "does the workspace exist?" check always saw it as present and skipped the copy.Fix
Capture
workspace_existed = workspace.exists()before callingstart(), and drive the bootstrap-copy decision off that pre-start snapshot, so a genuinely new workspace gets its bootstrap files.Test
bot/tests/test_sandbox_bootstrap.py(2 tests) — covers bootstrap copy on a fresh workspace vs. skip on a pre-existing one. Both pass.
