feat(opencode): unify code mode discovery under tools.$rune

Browse Source 
Remove Rune's vestigial built-in $rune.search/$rune.describe (which only
saw effect-Schema Definitions, never our dynamic MCP tools) and the
reserved-namespace guard. Move our ranked search and typed describe under
tools.$rune.* — the runtime's own namespace, separate from MCP server
namespaces and collision-proof since $ never appears in a sanitized
server name. One discovery implementation, no dead code.
