Update and expand error database

[naheel0]

Normalize and shorten existing error entries (clearer explanations, concise 'why' and 'fixes'), reformat examples, and add many common Node/JS/Mongo/JWT/CORS/HTTP error entries to lib/database.json for broader coverage and clearer troubleshooting guidance.

Poem

🐰 I dug through logs beneath the moonlit glen,

Found scattered errors, carrots in a pen,
I sorted them tidy, numbered each clue,
Hop, patch, and prune — now they all have a view,
A rabbit's small triumph, catalog complete.

any literal credentials and use a safe placeholder or non-credential form (e.g.,

environment variables rather than hardcoding credentials.
- Around line 43-48: Update the "explanation" text for the JSON entry whose
"name" is "RangeError: Maximum call stack size exceeded" (and "match" equals
"Maximum call stack size exceeded") to describe deep/unbounded call chains
rather than an "infinite loop" — e.g., state that the error is typically caused
by excessive recursion or very deep call stacks and suggest checking recursive
base cases and call-chain depth. Keep references to the existing keys ("name",
"match", "explanation", "fixes") and ensure the new "explanation" mentions
recursion/call-chain issues and suggests checking recursion exit conditions and
stack-building loops.
- Around line 219-224: The example for "PayloadTooLargeError" uses an invalid
Express API string ("app.use(express.limit('10mb'))"); update the example value
in the JSON entry for "PayloadTooLargeError" to use the correct Express
body-parser option by replacing the invalid API with a snippet that shows using
express.json with a limit option (i.e., demonstrate app.use(express.json({
limit: '<size>' })) rather than express.limit), and ensure the "fixes" array
suggestion likewise references using express.json({limit: '...'}) instead of
express.limit.
