feat(skills): expand touchdesigner-mcp with GLSL, post-FX, audio, geometry references (#13664)

Add 6 new reference files with generic reusable patterns:
- glsl.md: uniforms, built-in functions, shader templates, Bayer dither
- postfx.md: bloom, CRT scanlines, chromatic aberration, feedback glow
- layout-compositor.md: layoutTOP, overTOP grids, panel dividers
- operator-tips.md: wireframe rendering, feedback TOP setup
- geometry-comp.md: instancing, POP vs SOP rendering, shape morphing
- audio-reactive.md: band extraction (audiofilterCHOP), beat detection, MIDI

Expand pitfalls.md (#46-63):
- Connection syntax, moviefileoutTOP bug, batch frame capture
- TOP.save() time advancement, feedback masking, incremental builds
- MCP reconnection after project.load(), TOX reverse-engineering
- sliderCOMP naming, create() suffix requirement
- COMP reparenting (copyOPs), expressionCHOP crash
- Strip session-specific names in earlier pitfalls (promo_ -> my_)
- Audio device CHOP at FPS=0: active=False is the fix, not volume=0

All content is generic — no session-specific paths, hardware, aesthetics,
or param-name-only entries (those belong in td_get_par_info).
Bumps version 1.0.0 -> 1.1.0.

Salvaged from @kshitijk4poor's original PR #13664; dropped setup.sh and
troubleshooting.md changes that reverted subsequent HERMES_HOME and pgrep
fixes already on main, and preserved original author frontmatter.

+## Wireframe Rendering Pattern
+
+Reusable setup for wireframe geometry on black background:
+
+```python
+# 1. Material
+mat = root.create(wireframeMAT, 'wire_mat')
+mat.par.colorr = 1.0; mat.par.colorg = 0.0; mat.par.colorb = 0.0
+mat.par.linewidth = 3
+
+# 2. Geometry COMP
+geo = root.create(geometryCOMP, 'my_geo')
+geo.par.rx.expr = 'absTime.seconds * 30'
+geo.par.ry.expr = 'absTime.seconds * 45'
+geo.par.material = mat.path  # NOTE: 'material' not 'mat'
+
+# 3. Shape inside the geo
+box = geo.create(boxSOP, 'cube')
+box.par.sizex = 1.5; box.par.sizey = 1.5; box.par.sizez = 1.5
+
+# 4. Camera
+cam = root.create(cameraCOMP, 'cam1')
+cam.par.tx = 0; cam.par.ty = 0; cam.par.tz = 4; cam.par.fov = 45
+
+# 5. Render TOP
+render = root.create(renderTOP, 'render1')
+render.par.outputresolution = 'custom'
+render.par.resolutionw = 1280; render.par.resolutionh = 720
+render.par.bgcolorr = 0; render.par.bgcolorg = 0; render.par.bgcolorb = 0
+render.par.camera = cam.path
+render.par.geometry = geo.path
+
+# 6. Output null
+out = root.create(nullTOP, 'out1')
+out.inputConnectors[0].connect(render.outputConnectors[0])
+```
+
+**Key rules:**
+- Class names: `wireframeMAT` not `wireframeMat` (all-caps suffix)
+- Geometry SOPs/POPs go INSIDE the geo comp
+- Material: `geo.par.material` not `geo.par.mat`
+- Render geometry: `render.par.geometry = geo.path` (string path)
+- `wireframeMAT.par.wireframemode = 'topology'` for clean wireframe (vs `'tesselated'` for triangle edges)
+- Alternative: Use `renderTOP.par.overridemat` instead of per-geo material
+
+## Feedback TOP
+
+### Basic Structure
+
+```
+input (initial state) ──┐
+                        ├──→ feedback_top ──→ processing ──→ null_out
+                        │                                        ↑
+                        └── par.top = 'null_out' ────────────────┘
+```
+
+### Setup Pattern
+
+```python
+# 1. Processing chain
+glsl = root.create(glslTOP, 'sim')
+null_out = root.create(nullTOP, 'null_out')
+glsl.outputConnectors[0].connect(null_out.inputConnectors[0])
+
+# 2. Feedback referencing null_out
+feedback = root.create(feedbackTOP, 'feedback')
+feedback.par.top = 'null_out'
+
+# 3. Black initial state
+const_init = root.create(constantTOP, 'const_init')
+const_init.par.colorr = 0; const_init.par.colorg = 0; const_init.par.colorb = 0
+
+# 4. Wire: initial → feedback, feedback → processing
+feedback.inputConnectors[0].connect(const_init)
+glsl.inputConnectors[0].connect(feedback)
+
+# 5. Reset to apply initial state
+feedback.par.resetpulse.pulse()
+```
+
+### Common Errors
+
+| Error | Cause | Solution |
+|-------|-------|----------|
+| "Not enough sources specified" | No input connected | Connect initial state TOP |
+| Unexpected initial pattern | Wrong initial state | Use Constant TOP (black) |
+
+### Tips
+
+1. Use float format for simulations: `glsl.par.format = 'rgba32float'`
+2. Reset after setup: `feedback.par.resetpulse.pulse()`
+3. Match resolutions — feedback, processing, and initial state must match
+4. Soft boundary prevents edge artifacts:
+   ```glsl
+   float edge = 3.0 * texel.x;
+   float bx = smoothstep(0.0, edge, uv.x) * smoothstep(0.0, edge, 1.0 - uv.x);
+   float by = smoothstep(0.0, edge, uv.y) * smoothstep(0.0, edge, 1.0 - uv.y);
+   value *= bx * by;
+   ```
+
+### Use Cases
+- **Wave Simulation** — R=height, G=velocity, black initial state
+- **Cellular Automata** — white=alive, black=dead, random noise initial state
+- **Trail / Motion Blur** — blend current frame with feedback, black initial
