Implements three specialized URL-encoding modes tailored to Proxmox API quirks: path segments, API token values, and QEMU SSH keys. Uses a precomputed lookup table for efficiency. The package is isolated and could be extracted into any Go project needing custom percent-encoding rules for non-standard API path parameters.

Provides a declarative mock HTTP server for testing API clients without a live backend. It validates request parameters and returns canned responses, enabling realistic integration-style tests in unit tests. Although its request builders are Proxmox-flavored, the core server is a reusable pattern for any HTTP client test suite.

Defines a custom AuthorizedKey type with JSON marshal/unmarshal and URL encoding/decoding logic for OpenSSH authorized keys. It handles the awkward escaping Proxmox requires and is a self-contained example of a robust domain type that could be reused in other infrastructure tooling.

Contains snapshot CRUD plus a raw snapshot tree builder that reconstructs parent/child relationships from Proxmox snapshot metadata. The tree-building logic is generic enough to be lifted into any project needing hierarchical reconstruction from flat parent references, and is well-covered by tests.
