/**
 * Merges credential values field-by-field across sources, in priority order:
 * the current process's own environment, then this user's OS secret store,
 * then the Windows User environment.
 *
 * process.env stays first so a per-session override still behaves as expected,
 * and so CI keeps working unchanged. The secret store comes next because it is
 * the only source an editor launched from a Dock or Start menu can reach - such
 * a process never sourced a shell profile. The Windows User environment stays
 * last: a team member who only ever `setx`'d their token still boots without a
 * fresh terminal.
 *
 * Merging is per field, so a single exported variable can shadow one field of a
 * stored credential and leave the rest - `describe()` reports that as "mixed".
