Bump and clean up deps, raise min local node version

[Jake Bailey (jakebailey)]

I'm trying to update and prune our deps; this PR:

• Bumps adm-zip, no more audit error
• Removes tmp in favor of node's builtin tmpdir func
• Raises the min node for local dev to 22.18, removing --experimental-type-stripping everywhere
• Replaces glob with node's globbing
• Replaces picocolors with node's styleText
• Replaces p-limit with a small local helper
• Replaces execa with tinyexec
• Remove which
• Use @types/node@22 consistently
