Lightweight ETS-backed storage for runtime configuration.

The store keeps the latest routing tables, provider definitions, CLI configs, and other hot-reloadable artifacts so they can be accessed without disk I/O.

Stored Namespaces

• {:config, :routing} — Current RoutingTable
• {:config, :providers} — Map of %Definition{} structs keyed by provider id
• {:config, :cli_providers} — Map of %CLIProvider.Config{} structs keyed by atom name
• {:config, :telemetry} — Telemetry settings map
• {:config, :raw} — Raw merged TOML configuration

Access Patterns

Direct ETS reads (no GenServer call):

{:ok, table} = LlmCore.Config.Store.get_routing()
{:ok, providers} = LlmCore.Config.Store.fetch(:config, :providers)

Writes go through the GenServer for serialisation:

:ok = LlmCore.Config.Store.put_routing(%RoutingTable{...})
:ok = LlmCore.Config.Store.put(:config, :telemetry, %{...})
