Release 2.1.75 (2026-06-27)

Bug fixes

• drop redundant per-session tooling reinstall (#1902) vrg-vm session reinstalled vergil-tooling on every Lima session launch before exec claude, costing ~21s on a cold uv cache. This is redundant: create, rebuild, every start, and every update already install or refresh the tooling, so by the time a VM is sessionable its tooling is current.

Remove the per-session try_update_tooling call from _cmd_session and delete the now-orphaned try_update_tooling helper (its only production caller) from vm_guest, along with its dedicated tests. update_tooling stays; it has other callers.

The accepted trade-off: a VM left running across a release the sweep missed runs stale tooling until the next start/update/rebuild, handled out of band.
