Add FastDevTool to Web Tools section

What

Add FastDevTool to the Web Tools section.

Why

FastDevTool is a collection of 50+ free developer utilities (JSON formatter/beautifier, Base64, URL encoder, JWT decoder, Regex tester, UUID generator, Hash generator, SQL formatter, and more) that run entirely in the browser with no server processing.

What makes it different:

• Uses Monaco editor (VS Code's engine) — syntax highlighting, error squiggles, ⌘F search
• Shareable URLs via client-side pako compression (no server, links never expire)
• Offline support via PWA
• Local input history saved in localStorage
• 100% client-side — no data sent to any server

Placed after the ExtendsClass entry as it serves a similar audience.

Thanks for the review!

Reason: Developers often need multiple formatting/conversion tools in one session (e.g. decode
a JWT, format the JSON payload, validate it against a schema). FastDevTool covers 50+ of these
utilities under one domain — no tab-switching between different sites.

Alternatives considered:

• transform.tools — great for format conversion but limited scope (~20 tools)
• freeformatter.com / codebeautify.org — server-side processing; not ideal when working with
  sensitive data (tokens, credentials, internal API payloads)

Why this fits the list: The key differentiator is 100% client-side execution — no data ever
leaves the browser. All editors are powered by Monaco (the same engine behind VS Code), giving
developers syntax highlighting, error squiggles, and ⌘F search they're already familiar with.
It also works offline via PWA and requires zero signup. That aligns well with the "secret
knowledge" audience who value privacy and efficiency.
