chore(cli): migrate @fern-api/remote-workspace-runner to use CliError

[FedeZara]

Description

Migrates @fern-api/remote-workspace-runner to use explicit CliError error codes on every failAndThrow / failWithoutThrowing call site.

This is one of the package migration PRs that follow the error classification system introduced in #14749.

Changes Made

Assigned typed error codes across call sites in packages/cli/generation/remote-generation/remote-workspace-runner/src/. Also added missing CliError imports to all files that reference CliError.Code.

Error codes used

Code	Usage
NETWORK_ERROR	HTTP/API call failures, job creation errors, source upload failures
CONFIG_ERROR	Invalid generation configuration, missing required fields
CONTAINER_ERROR	Remote container execution failures
INTERNAL_ERROR	Unexpected job states, polling failures

Files touched (grouped by area)

• Job management: createAndStartJob.ts, pollJobAndReportStatus.ts
• Generation: runRemoteGenerationForAPIWorkspace.ts, runRemoteGenerationForDocsWorkspace.ts, runRemoteGenerationForGenerator.ts
• Publishing: publishDocs.ts
• Task handling: RemoteTaskHandler.ts, SourceUploader.ts

Testing

• Existing tests pass (pnpm test, excluding e2e and pre-existing environment failures)
