Extract client SDK package (#1052)
* Extract client SDK package * Polish SDK client identity defaults * Build client before dependent CI jobs * Restore daemon client server export * Extract protocol and client SDK packages * Fix provider override schema validation * Fix app test daemon client imports * Simplify workspace build targets * Fix CLI test server build bootstrap * Run SDK package tests in CI * Fix rebase package split drift * Restore lockfile registry metadata * Update SDK config test for prompt default * Move terminal stream router test to client package * Fix rebase drift for protocol imports * Fix SDK agent capability fixture * Restore legacy server client exports * Fix server export compatibility test * Advertise custom mode icon client capability * Remove server daemon-client exports * Format rebased mode control import * Fix rebase drift for protocol imports Files added by upstream PRs (#893, #1147, #1154) referenced the pre-split shared/ paths that this branch moves into @getpaseo/protocol. Redirect those imports to the protocol package so typecheck stays green after the rebase.
