Add path filters to CI workflows and create UI test workflow

[mostlygeek]

Summary

This PR optimizes CI/CD workflows by adding path-based filters to reduce unnecessary workflow runs and introduces a new dedicated workflow for UI testing.

Key Changes

• Go CI Workflows: Added path filters to go-ci.yml and go-ci-windows.yml to only trigger on changes to:

  • Go source files (**/*.go)
  • Go module files (go.mod, go.sum)
  • Build configuration (Makefile)
  • Excludes changes in cmd/** directory

• New UI Test Workflow: Created ui-tests.yml workflow that:

  • Runs on changes to ui-svelte/** directory only
  • Sets up Node.js 23 with npm caching
  • Executes type checking (npm run check)
  • Runs test suite (npm test)
  • Uses ubuntu-latest runner

Benefits

• Reduces CI/CD overhead by skipping unrelated workflow runs
• Provides faster feedback for UI-specific changes
• Maintains separate testing pipelines for Go backend and Svelte frontend
• Improves developer experience with more targeted test execution

Summary by CodeRabbit

• Chores

  • CI workflows for Windows and Linux now only run for relevant backend source and build changes, reducing unnecessary runs.
  • Release workflow updated to use Node.js 24.

• New Features

  • Added an automated UI testing workflow that runs type checks and frontend tests for UI changes.

• Bug Fixes

  • Speech playground no longer stores/display generated text state, simplifying audio handling.

Walkthrough

Adds path-based filters to Linux and Windows Go CI workflows, introduces a new "UI Tests" workflow for ui-svelte, bumps Node.js in the release workflow from 23 to 24, and removes generatedText and clearAudio handling from SpeechInterface.svelte.

Changes

Cohort / File(s)	Summary
Go CI Path Filtering \.github/workflows/go-ci.yml, \.github/workflows/go-ci-windows.yml	Added path filters to push and pull_request triggers: include **/*.go, exclude cmd/**, and explicitly include go.mod, go.sum, Makefile, and the workflow file(s).
UI Tests Workflow \.github/workflows/ui-tests.yml	New workflow UI Tests targeting ui-svelte: triggers on pushes/PRs to main for ui-svelte/** and the workflow file; runs on ubuntu-latest, sets up Node.js 24, installs with npm ci, runs type checks and tests.
Release Workflow \.github/workflows/release.yml	Updated Node.js setup from version 23 to 24.
UI Component ui-svelte/src/components/playground/SpeechInterface.svelte	Removed generatedText state and its assignment/clearing; removed clearAudio() that revoked/cleared generated text and related state.

In @.github/workflows/ui-tests.yml:
- Around line 26-31: The workflow is using Node.js 23 which is end-of-life; edit
the GitHub Actions job that calls actions/setup-node@v4 and change the
node-version value from '23' to a supported release (preferably '24') so CI uses
Node.js 24; ensure the node-version: '23' line in the UI tests step is updated
to node-version: '24' (no other changes required).

8-13: Consider including workflow file changes in path filters.

Changes to .github/workflows/go-ci-windows.yml itself won't trigger this workflow. If workflow logic changes, you'd need to manually trigger via workflow_dispatch to verify the changes work correctly.

Consider adding the workflow file to the paths:

     paths:
       - '**/*.go'
       - '!cmd/**'
       - 'go.mod'
       - 'go.sum'
       - 'Makefile'
+      - '.github/workflows/go-ci-windows.yml'
