fix(server): make callable extension type augmentation work in published builds

[keithf123r]

Problem

import '@orpc/server/extensions/callable' works at runtime, but in the published package .callable() fails type-checking:

Property 'callable' does not exist on type 'DecoratedProcedure<...>'

Root cause

The source augments declare module '../procedure-decorated', which declaration bundling rewrites to declare module "../index". That extensionless path resolves to dist/index.d.ts, while consumers get their types from dist/index.d.mts via the exports map — so the augmentation merges into a module the consumer never uses.

The monorepo never sees this because dev exports point at src.

Fix

Augment declare module '@orpc/server' instead, matching every other extension in the repo (next, effect, openapi). The bare specifier survives bundling and resolves to the same entry the consumer imports.

Verification

• pnpm test and pnpm type:check pass
• The built dist works

• callable.ts module augmentation fix — Changes the module augmentation target from a relative path (../procedure-decorated) to the bare package specifier (@orpc/server), matching the pattern used by every other extension (@orpc/effect, @orpc/next, @orpc/openapi).
