lab build lab rebuilds and reinstalls the running lab binary. The install step cp-ed over ~/.local/bin/lab without unlinking it first, so overwriting the in-use executable failed with ETXTBSY ("Text file busy").

Fix: rm -f the destination before cp in lab_build.sh — unlink succeeds while the open inode keeps the running process alive, so the new binary installs cleanly.

Verified: a plain lab build lab --restart --install now builds and installs end-to-end.

`lab build lab` rebuilds and reinstalls the *running* `lab` binary. The install step `cp`-ed over `~/.local/bin/lab` without unlinking it first, so overwriting the in-use executable failed with `ETXTBSY` ("Text file busy"). Fix: `rm -f` the destination before `cp` in `lab_build.sh` — unlink succeeds while the open inode keeps the running process alive, so the new binary installs cleanly. Verified: a plain `lab build lab --restart --install` now builds and installs end-to-end.
