docs(website): dedicated page per bundled + optional skill (#14929)

Generates a full dedicated Docusaurus page for every one of the 132 skills
(73 bundled + 59 optional) under website/docs/user-guide/skills/{bundled,optional}/<category>/.
Each page carries the skill's description, metadata (version, author, license,
dependencies, platform gating, tags, related skills cross-linked to their own
pages), and the complete SKILL.md body that Hermes loads at runtime.

Previously the two catalog pages just listed skills with a one-line blurb and
no way to see what the skill actually did — users had to go read the source
repo. Now every skill has a browsable, searchable, cross-linked reference in
the docs.

- website/scripts/generate-skill-docs.py — generator that reads skills/ and
  optional-skills/, writes per-skill pages, regenerates both catalog indexes,
  and rewrites the Skills section of sidebars.ts. Handles MDX escaping
  (outside fenced code blocks: curly braces, unsafe HTML-ish tags) and
  rewrites relative references/*.md links to point at the GitHub source.
- website/docs/reference/skills-catalog.md — regenerated; each row links to
  the new dedicated page.
- website/docs/reference/optional-skills-catalog.md — same.
- website/sidebars.ts — Skills section now has Bundled / Optional subtrees
  with one nested category per skill folder.
- .github/workflows/{docs-site-checks,deploy-site}.yml — run the generator
  before docusaurus build so CI stays in sync with the source SKILL.md files.

Build verified locally with `npx docusaurus build`. Only remaining warnings
are pre-existing broken link/anchor issues in unrelated pages.

+
+# Blender Mcp
+
+Control Blender directly from Hermes via socket connection to the blender-mcp addon. Create 3D objects, materials, animations, and run arbitrary Blender Python (bpy) code. Use when user wants to create or modify anything in Blender.
+

+:::info
+The following is the complete skill definition that Hermes loads when this skill is triggered. This is what the agent sees as instructions when the skill is active.
+:::
+
+# Blender MCP
+
+Control a running Blender instance from Hermes via socket on TCP port 9876.
+
+## Setup (one-time)
+
+### 1. Install the Blender addon
+
+    curl -sL https://raw.githubusercontent.com/ahujasid/blender-mcp/main/addon.py -o ~/Desktop/blender_mcp_addon.py
+
+In Blender:
+    Edit > Preferences > Add-ons > Install > select blender_mcp_addon.py
+    Enable "Interface: Blender MCP"
+
+### 2. Start the socket server in Blender
+
+Press N in Blender viewport to open sidebar.
+Find "BlenderMCP" tab and click "Start Server".
+
+### 3. Verify connection
+
+    nc -z -w2 localhost 9876 && echo "OPEN" || echo "CLOSED"
+
+## Protocol
+
+Plain UTF-8 JSON over TCP -- no length prefix.
+
+Send:     {"type": "<command>", "params": {<kwargs>}}
+Receive:  {"status": "success", "result": <value>}
+          {"status": "error",   "message": "<reason>"}
+
+## Available Commands
+
+| type                    | params            | description                     |
+|-------------------------|-------------------|---------------------------------|
+| execute_code            | code (str)        | Run arbitrary bpy Python code   |
+| get_scene_info          | (none)            | List all objects in scene       |
+| get_object_info         | object_name (str) | Details on a specific object    |
+| get_viewport_screenshot | (none)            | Screenshot of current viewport  |
+
+## Python Helper
+
+Use this inside execute_code tool calls:
+
+    import socket, json
+
+    def blender_exec(code: str, host="localhost", port=9876, timeout=15):
+        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+        s.connect((host, port))
+        s.settimeout(timeout)
+        payload = json.dumps({"type": "execute_code", "params": {"code": code}})
+        s.sendall(payload.encode("utf-8"))
+        buf = b""
+        while True:
+            try:
+                chunk = s.recv(4096)
+                if not chunk:
+                    break
+                buf += chunk
+                try:
+                    json.loads(buf.decode("utf-8"))
+                    break
+                except json.JSONDecodeError:
+                    continue
+            except socket.timeout:
+                break
+        s.close()
+        return json.loads(buf.decode("utf-8"))
+
+## Common bpy Patterns
+
+### Clear scene
+    bpy.ops.object.select_all(action='SELECT')
+    bpy.ops.object.delete()
+
+### Add mesh objects
+    bpy.ops.mesh.primitive_uv_sphere_add(radius=1, location=(0, 0, 0))
+    bpy.ops.mesh.primitive_cube_add(size=2, location=(3, 0, 0))
+    bpy.ops.mesh.primitive_cylinder_add(radius=0.5, depth=2, location=(-3, 0, 0))
+
+### Create and assign material
+    mat = bpy.data.materials.new(name="MyMat")
+    mat.use_nodes = True
+    bsdf = mat.node_tree.nodes.get("Principled BSDF")
+    bsdf.inputs["Base Color"].default_value = (R, G, B, 1.0)
+    bsdf.inputs["Roughness"].default_value = 0.3
+    bsdf.inputs["Metallic"].default_value = 0.0
+    obj.data.materials.append(mat)
+
+### Keyframe animation
+    obj.location = (0, 0, 0)
+    obj.keyframe_insert(data_path="location", frame=1)
+    obj.location = (0, 0, 3)
+    obj.keyframe_insert(data_path="location", frame=60)
+
+### Render to file
+    bpy.context.scene.render.filepath = "/tmp/render.png"
+    bpy.context.scene.render.engine = 'CYCLES'
+    bpy.ops.render.render(write_still=True)
+
+## Pitfalls
+
+- Must check socket is open before running (nc -z localhost 9876)
+- Addon server must be started inside Blender each session (N-panel > BlenderMCP > Connect)
+- Break complex scenes into multiple smaller execute_code calls to avoid timeouts
+- Render output path must be absolute (/tmp/...) not relative
+- shade_smooth() requires object to be selected and in object mode
