/**
 * Case-insensitively rewrite list-filter values to their canonical enum
 * forms before the request hits the Harness API.
 *
 * Agents often send lowercase (`"pending"`) when APIs require PascalCase
 * (`"Pending"`) or UPPERCASE (`"CONNECTED"`). Enum metadata lives on
 * `listFilterFields` and is surfaced via `harness_describe`, but the
 * global `harness_list` schema cannot encode per-resource enums — so
 * canonicalize here instead of relying on agents to call describe first.
 *
 * - Case-insensitive match → rewrite to the declared enum value
 * - Comma-separated multi-values are canonicalized token-by-token
 * - Non-string values are left untouched (typed filters stay as-is)
 *
 * Values with no case-insensitive match are passed through unchanged.
 * `listFilterFields.enum` is hand-maintained documentation metadata that
 * can lag the API, and some resources apply their own fallback for
 * unrecognized values, so this must not become a validation gate.
