refactor: add the vt_ prefix to unprefixed crates

[wan9chi]

Motivation

With this, every crate in the workspace carries one of its two prefixes, vt_ or fspy_, so a crate's name says it belongs to vite-task. Names like socket_ipc, snapshot_test or subprocess_test otherwise read like third-party crates, here and in workspaces that depend on these crates, such as vite-plus.

Renamed, along with their directories:

• materialized_artifact, materialized_artifact_macros
• preload_test_lib
• pty_terminal, pty_terminal_test, pty_terminal_test_client
• snapshot_test
• socket_ipc
• subprocess_test

vt and fspy are the prefixes themselves, so they keep their names. Runtime names derived from the old crate names, such as the socket_ipc_ socket prefix and the pty-terminal-test: milestone marker, stay as they are.

vite-plus depends on pty_terminal_test, pty_terminal_test_client, and snapshot_test by name, so its next vite-task bump needs to switch to the new names.
