feat(config): merge platform config model and add disabled-platform guard (#336)

Browse source 
## Problem

Supplying any `platforms` table silently dropped all unlisted platforms,
making it easy to accidentally disable platforms. Invoking a disabled
platform produced no user-facing error.

## Solution

Switch to a merge model: all six platforms are enabled by default and
user entries are deep-merged on top. Set a platform key to `false` to
disable it explicitly. Add a `check_platform_enabled` guard in
`handle_command` for contest fetch, login, logout, and race actions.
