feat: Add attribution replacement example alongside bun replacement

This commit expands the Terraphim-Claude integration with a second
use case: replacing Claude Code attribution with Terraphim AI attribution.

Changes:
- Fixed docs/src/kg/knowledge-graph-system.md to prevent documentation
  synonym examples from being parsed as actual KG entries (caused
  every character to be replaced with "knowledge-graph-system")
- Added new KG files for attribution replacement:
  - terraphim_ai.md - Maps "Claude Code" → terraphim_ai
  - https___terraphim_ai.md - Maps Claude URLs → Terraphim URLs
  - generated_with_terraphim.md - Maps generation attribution text
  - noreply_terraphim.md - Maps email addresses
- Updated TERRAPHIM_CLAUDE_INTEGRATION.md with both examples
- Documented filename-based replacement limitation (spaces → underscores)

Both use cases now work:
1. Package manager: "npm install" → "bun_install"
2. Attribution: "[Claude Code]..." → "[terraphim_ai]..."

The replacements use filename stems as replacement text, so spaces
become underscores and special characters are converted. This is a
fundamental design where filenames serve as normalized terms.

+### Real-World Examples
+
+**1. Package Manager Replacement (bun)**
+
+Knowledge Graph Files:
+- `docs/src/kg/bun.md` - Maps npm/yarn/pnpm → bun
+- `docs/src/kg/bun_install.md` - Maps installation commands → bun_install
+
+Example Replacements:
+```bash
+$ terraphim-tui replace "npm install && yarn test"
+bun_install && bun test
+```
+
+**2. Attribution Replacement (Claude → Terraphim)**
+
+Knowledge Graph Files:
+- `docs/src/kg/terraphim_ai.md` - Maps "Claude Code" → terraphim_ai
+- `docs/src/kg/https___terraphim_ai.md` - Maps Claude URLs → Terraphim URLs
+- `docs/src/kg/generated_with_terraphim.md` - Maps attribution text
+- `docs/src/kg/noreply_terraphim.md` - Maps email addresses
+
+Example Replacements:
+```bash
+$ terraphim-tui replace "🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>"
+🤖 Generated with [terraphim_ai](https___terraphim_ai) Co-Authored-By: terraphim_ai <noreply_terraphim>
+```
+
+**Note on Output Format**: Replacement text uses filename stems, so spaces become underscores and special characters are converted (e.g., "https://terraphim.ai" → "https___terraphim_ai"). This is a fundamental design of the system where filenames serve as normalized replacement terms.
