Add HuggingFace audio and media generation tasks

[anishshiva7]

Task Summary

Feature Summary

The HuggingFace inference operator (#5041) is being landed as a sequence of focused task-family PRs. The dispatcher + per-task codegen architecture was introduced in #5277 with text-generation as the first task family.

This issue covers adding the audio and media-generation task families to that architecture. The new tasks plug into the existing dispatcher by adding dedicated TaskCodegen implementations for audio and media generation, then registering their task strings in HuggingFaceInferenceOpDesc.

Concretely, landing this would enable:

• Audio inference tasks:
  • automatic-speech-recognition
  • audio-classification
  • text-to-speech
• Media-generation tasks:
  • text-to-image
  • text-to-video
• A cleaner codegen structure where audio and media-generation Python payload / parse logic lives in separate files instead of expanding the operator descriptor.

Proposed Solution or Design

Add new files under:

common/workflow-operator/src/main/scala/org/apache/texera/amber/operator/huggingFace/codegen/

File	Purpose
AudioTaskCodegen.scala	Payload and response parsing for ASR, audio-classification, and text-to-speech
MediaGenCodegen.scala	Payload and response parsing for text-to-image and text-to-video

Modify:

File	Change
HuggingFaceInferenceOpDesc.scala	Add audio input fields and register the new task codegens
TaskCodegen.scala	Extend CodegenContext with audio input fields
PythonCodegenBase.scala	Add shared audio/media helpers, audio source resolution, raw audio body support, and media data URL handling
HuggingFaceInferenceOpDescSpec.scala	Add descriptor/codegen coverage for audio and media-generation tasks

Design constraints:

• Follow the dispatcher pattern from Add HuggingFaceInferenceOpDesc with dispatcher + per-task codegen architecture (text-generation) #5277.
• Keep task-specific Python generation in separate TaskCodegen files.
• Preserve EncodableString + pyb"..." safety for user-provided string fields.
• Keep generatePythonCode total so arbitrary @JsonProperty values do not throw during code generation.
• Normalize media responses into data URLs where applicable so downstream result rendering can consume image, audio, and video outputs consistently.

Impact / Priority

(P2) Medium — required for broader HuggingFace operator task coverage. Does not affect existing operators.

Affected Area

Workflow Engine (Amber) — HuggingFace operator descriptor and Python codegen.

👋 Thanks for your first contribution to Texera, @anishshiva7!

You can drive common housekeeping tasks just by leaving a comment. Type the command on its own line.

On issues

Command	What it does
/take	Assign the issue to yourself (self-claim it)
/untake	Remove yourself as assignee

To find unclaimed work, search is:issue is:open no:assignee — there's no "triage" label; the search filter is the triage state.

Linking sub-issues

Command	Where to run it	What it does
/sub-issue #12 #13	On the parent	Links #12 and #13 as children of this issue
/unsub-issue #12 #13	On the parent	Unlinks those children
/parent-issue #5	On the child	Sets #5 as this issue's parent
/unparent-issue	On the child	Removes this issue's parent (auto-detected)
/unparent-issue #5	On the child	Removes parent #5 explicitly

You can write references as #12 or bare 12. Cross-repo references like owner/repo#12 aren't supported and are ignored.

On pull requests (author only)

Command	What it does
/request-review @user [@user ...]	Request reviews from those users
/unrequest-review @user [@user ...]	Cancel those review requests

You can mention teams as @org/team, and @copilot works too. Only the PR author can use these commands.

Note: Commands must match exactly — /take this won't work, only /take. Bots are ignored, and you can't self-link an issue or set an issue as its own parent.

For the full contribution flow, see CONTRIBUTING.md.
