Replaces synchronous `fs.readFileSync` with `fs.promises.readFile` in `loadTorchConfig` to prevent event loop blocking.
Updates all dependent configuration getters and consumers to use async/await.
Includes benchmark proving non-blocking behavior.

- Introduced `parseStringList` helper to handle parsing of string arrays from config.
- Replaced `parseRelayList` and `parseRoster` with `parseStringList`.
- Replaced inline parsing of `relays` and `dashboard.relays` with `parseStringList`.
- Unified behavior: empty lists in config now consistently return `null` instead of `[]`.
- Added unit test verifying consistent `null` return for empty lists.

Refactored `loadTorchConfig` to support dependency injection for `fs`, enabling true unit tests without disk I/O. Added comprehensive unit tests in `test/torch-config-unit.test.mjs`.
- Refactored `loadTorchConfig` to accept optional `fileSystem` argument.
- Created `test/torch-config-unit.test.mjs` with mocked fs tests.
- Verified existing tests pass.
