perf: [PRODUCT-576] refactor sf nodes to use GET v1/nodes/list?names=...

[sigmachirality]

Refactor sf nodes set, release, extend to use API filtering and add sf nodes get for efficient node retrieval.

Also fixes sf extend which erroneously assumes users will always extend from NOW. Makes the code for sf extend more resilient in general.

Adds sf nodes show/get.

Greptile Summary

This PR implements a significant refactoring of the SFCompute CLI to optimize node operations and expand VM management capabilities. The core change involves moving from client-side filtering (fetching all nodes, then filtering locally) to server-side filtering using the API's names parameter (GET v1/nodes/list?names=...). This optimization is applied across multiple node commands including set, release, and extend.

The PR also introduces a new sf nodes get command that allows users to retrieve detailed information about specific nodes by name, leveraging the same API filtering for efficient data retrieval. The extend functionality has been made more resilient by fixing assumptions about extension timing and improving error handling for auto-reserved nodes.

Expanding the VM management suite, the PR adds comprehensive VM image management commands (sf vm images list/upload/show) behind the custom-vm-images feature flag, along with new VM operations like sf vm logs, sf vm replace, and sf vm script. The VM module has been restructured from a monolithic 477-line file into a modular directory structure with separate files for each command.

Additional enhancements include cloud-init user data support in node creation, multipart upload functionality for VM images with progress tracking and retry mechanisms, and various UI improvements like better error handling and more informative output formatting. The schema has been updated to remove admin-specific endpoints while adding new VM image management endpoints.

Confidence score: 2/5

• This PR contains several critical issues including potential runtime crashes and broken functionality that require immediate attention before merging
• Score lowered due to a critical bug in src/lib/nodes/release.ts that removes ID-based node lookup, potential runtime crash in src/lib/vm/list.ts, and magic numbers that should be extracted as constants
• Pay close attention to src/lib/nodes/release.ts, src/lib/vm/list.ts, and src/lib/vm/image/upload.ts

Context used:

Rule - Extract magic numbers into named constants at the top of files with documentation comments explaining their purpose and units. (link)
