8/// Validates a daemon ID to ensure it's safe for use in file paths and IPC.
9///
10/// A valid daemon ID:
11/// - Is not empty
12/// - Does not contain backslashes (`\`)
13/// - Does not contain parent directory references (`..`)
14/// - Does not contain spaces
15/// - Does not contain `--` (reserved for path encoding of `/`)
16/// - Is not `.` (current directory)
17/// - Contains only printable ASCII characters
18/// - If qualified (contains `/`), has exactly one `/` separating namespace and short ID
19///
20/// Format: `[namespace/]short_id`
21/// - Qualified: `project/api`, `global/web`
22/// - Short: `api`, `web`
23///
24/// This validation prevents path traversal attacks when daemon IDs are used
25/// to construct log file paths or other filesystem operations.

33
34/// Converts a daemon ID to a filesystem-safe path component.
35///
36/// Replaces `/` with `--` to avoid issues with filesystem path separators.
37///
38/// Examples:
39/// - `"api"` → `"api"`
40/// - `"global/api"` → `"global--api"`
41/// - `"project-a/api"` → `"project-a--api"`

47///
48/// The path is computed as: `$PITCHFORK_LOGS_DIR/{safe_id}/{safe_id}.log`
49/// where `safe_id` has `/` replaced with `--` for filesystem safety.
50///
51/// Prefer using `DaemonId::log_path()` when you have a structured ID.
