Greptile Summary

This PR refreshes the dependencies and Morph snapshots used by sandbox environments. The main changes are:

• Updates five IDE extension versions.
• Updates seven globally installed CLI package versions.
• Adds version 75 snapshots for the active 4-vCPU and 8-vCPU presets.

Confidence Score: 4/5

Persisted environment-creation state can fail validation after the snapshot rollover.

• The new entries satisfy the snapshot schema and ordering rules.
• Latest-snapshot selection correctly activates version 75.
• The strict client-side snapshot enum no longer accepts the prior latest IDs retained by the manifest.

packages/shared/src/morph-snapshots.json and the environment creation snapshot-ID validation

Important Files Changed

Filename	Overview
configs/ide-deps.json	Updates the pinned IDE extension and global CLI package versions.
packages/shared/src/morph-snapshots.json	Adds valid version 75 entries, but the rollover invalidates persisted environment-creation inputs containing the former latest snapshot IDs.

Previous Snapshot IDs Become Invalid

Adding version 75 replaces snapshot_9qig5lrf in the latest-ID list used by the environment creation route's strict z.enum. A bookmarked URL or persisted form containing that previously valid ID now fails search-parameter validation, even though the manifest still retains the snapshot as a supported historical version.
