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.

+# Codebase Inspection
+
+Inspect and analyze codebases using pygount for LOC counting, language breakdown, and code-vs-comment ratios. Use when asked to check lines of code, repo size, language composition, or codebase stats.

+# Codebase Inspection with pygount
+
+Analyze repositories for lines of code, language breakdown, file counts, and code-vs-comment ratios using `pygount`.
+
+## When to Use
+
+- User asks for LOC (lines of code) count
+- User wants a language breakdown of a repo
+- User asks about codebase size or composition
+- User wants code-vs-comment ratios
+- General "how big is this repo" questions
+
+## Prerequisites
+
+```bash
+pip install --break-system-packages pygount 2>/dev/null || pip install pygount
+```
+
+## 1. Basic Summary (Most Common)
+
+Get a full language breakdown with file counts, code lines, and comment lines:
+
+```bash
+cd /path/to/repo
+pygount --format=summary \
+  --folders-to-skip=".git,node_modules,venv,.venv,__pycache__,.cache,dist,build,.next,.tox,.eggs,*.egg-info" \
+  .
+```
+
+**IMPORTANT:** Always use `--folders-to-skip` to exclude dependency/build directories, otherwise pygount will crawl them and take a very long time or hang.
+
+## 2. Common Folder Exclusions
+
+Adjust based on the project type:
+
+```bash
+# Python projects
+--folders-to-skip=".git,venv,.venv,__pycache__,.cache,dist,build,.tox,.eggs,.mypy_cache"
+
+# JavaScript/TypeScript projects
+--folders-to-skip=".git,node_modules,dist,build,.next,.cache,.turbo,coverage"
+
+# General catch-all
+--folders-to-skip=".git,node_modules,venv,.venv,__pycache__,.cache,dist,build,.next,.tox,vendor,third_party"
+```
+
+## 3. Filter by Specific Language
+
+```bash
+# Only count Python files
+pygount --suffix=py --format=summary .
+
+# Only count Python and YAML
+pygount --suffix=py,yaml,yml --format=summary .
+```
+
+## 4. Detailed File-by-File Output
+
+```bash
+# Default format shows per-file breakdown
+pygount --folders-to-skip=".git,node_modules,venv" .
+
+# Sort by code lines (pipe through sort)
+pygount --folders-to-skip=".git,node_modules,venv" . | sort -t$'\t' -k1 -nr | head -20
+```
+
+## 5. Output Formats
+
+```bash
+# Summary table (default recommendation)
+pygount --format=summary .
+
+# JSON output for programmatic use
+pygount --format=json .
+
+# Pipe-friendly: Language, file count, code, docs, empty, string
+pygount --format=summary . 2>/dev/null
+```
+
+## 6. Interpreting Results
+
+The summary table columns:
+- **Language** — detected programming language
+- **Files** — number of files of that language
+- **Code** — lines of actual code (executable/declarative)
+- **Comment** — lines that are comments or documentation
+- **%** — percentage of total
+
+Special pseudo-languages:
+- `__empty__` — empty files
+- `__binary__` — binary files (images, compiled, etc.)
+- `__generated__` — auto-generated files (detected heuristically)
+- `__duplicate__` — files with identical content
+- `__unknown__` — unrecognized file types
+
+## Pitfalls
+
+1. **Always exclude .git, node_modules, venv** — without `--folders-to-skip`, pygount will crawl everything and may take minutes or hang on large dependency trees.
+2. **Markdown shows 0 code lines** — pygount classifies all Markdown content as comments, not code. This is expected behavior.
+3. **JSON files show low code counts** — pygount may count JSON lines conservatively. For accurate JSON line counts, use `wc -l` directly.
+4. **Large monorepos** — for very large repos, consider using `--suffix` to target specific languages rather than scanning everything.
