/**
 * The single on-disk document at `~/.reclaim/config.json`. Each top-level
 * key is an independent section owned by a different subsystem:
 *   - `mode`          — persisted backend preference (old-devtools vs builder),
 *                       set via the `set_devtools_mode` tool. Applied at server
 *                       start; an explicit `USE_OLD_DEVTOOLS` env var overrides
 *                       it (see `resolveOldMode` in consts.ts).
 *   - `browser_agent` — Chrome attach mode/port (the agent tools)
 *   - `session`       — the auth bearer token (authenticate)
 *   - `old_devtools`  — externally-supplied identity for OLD-devtools mode
 *                       (USE_OLD_DEVTOOLS); independent of `session`'s
 *                       builder token. Deletable with the rest of `src/old/`.
 * Sections are persisted independently via `ConfigStore.write`, which
 * merges rather than replaces, so one subsystem never clobbers another's.
 *
 * NOTE: eth proof-owner keys are NOT cached here — they live as PEMs in the
 * project (see authenticate/eth-key.ts). This config holds no private keys
 * other than the (short-lived) session bearer token.
