fix: update DiffRhythm workflows with correct node names and parameters
Updated all 4 DiffRhythm workflow JSON files to use actual node class names from ComfyUI_DiffRhythm:

**Node Name Changes:**
- DiffRhythmTextToMusic → DiffRhythmRun
- DiffRhythmRandomGeneration → DiffRhythmRun (with empty style_prompt)
- DiffRhythmReferenceBasedGeneration → DiffRhythmRun (with audio input)

**Corrected Parameter Structure:**
All workflows now use proper widgets_values array matching DiffRhythmRun INPUT_TYPES:
1. model (string: "cfm_model_v1_2.pt", "cfm_model.pt", or "cfm_full_model.pt")
2. style_prompt (string: multiline text or empty for random)
3. unload_model (boolean: default true)
4. odeint_method (string: "euler", "midpoint", "rk4", "implicit_adams")
5. steps (int: 1-100, default 30)
6. cfg (int: 1-10, default 4)
7. quality_or_speed (string: "quality" or "speed")
8. seed (int: -1 for random, or specific number)
9. edit (boolean: default false)
10. edit_segments (string: "[-1, 20], [60, -1]")

**Workflow-Specific Updates:**

**diffrhythm-simple-t2m-v1.json:**
- Text-to-music workflow for 95s generation
- Uses cfm_model_v1_2.pt with text prompt guidance
- Default settings: steps=30, cfg=4, speed mode, seed=42

**diffrhythm-full-length-t2m-v1.json:**
- Full-length 4m45s (285s) generation
- Uses cfm_full_model.pt for extended compositions
- Quality mode enabled for better results
- Default seed=123

**diffrhythm-reference-based-v1.json:**
- Reference audio + text prompt workflow
- Uses LoadAudio node connected to style_audio_or_edit_song input
- Higher cfg=5 for stronger prompt adherence
- Demonstrates optional audio input connection

**diffrhythm-random-generation-v1.json:**
- Pure random generation (no prompt/guidance)
- Empty style_prompt string
- Minimal cfg=1 for maximum randomness
- Random seed=-1 for unique output each time

**Documentation Updates:**
- Removed PLACEHOLDER notes
- Updated usage sections with correct parameter descriptions
- Added notes about optional MultiLineLyricsDR node for lyrics
- Clarified parameter behavior and recommendations

These workflows are now ready to use in ComfyUI with the installed DiffRhythm extension.
