docs: add debugging error lookup table

[GHX5T-SOL]

Addresses the common-error-message table slice of #1878.

What changed:

• Added a Common Error Messages section to docs/debugging.md.
• Linked it from the existing table of contents.
• Mapped recurring daemon/node error fragments to likely causes and next diagnostic commands.

Validation:

• git diff origin/main..HEAD --check
• git show --format= --patch HEAD | gitleaks stdin --no-banner --redact --timeout 30 -> no leaks found

Not run: cargo tests; docs-only change.
