Add comprehensive bash script tests and fix old mcp/ path references

- Created tests/test_setup_scripts.py with 19 tests covering:
  * setup_mcp.sh validation (11 tests)
  * General bash script quality (4 tests)
  * MCP path consistency across codebase (4 tests)

- Fixed old 'mcp/' references in documentation:
  * docs/B1_COMPLETE_SUMMARY.md (3 refs)
  * docs/PDF_MCP_TOOL.md (2 refs)
  * docs/MCP_SETUP.md (18 refs)
  * docs/TEST_MCP_IN_CLAUDE_CODE.md (4 refs)

These tests would have caught Issue #157 before it reached users.

Tests verify:
- Bash syntax validity
- No hardcoded paths
- Correct skill_seeker_mcp/ directory references
- Files referenced in scripts actually exist
- No deprecated backticks
- Proper error handling (set -e)

All 19 tests passing ✅
