Closes #24

Description

Adds a custom algoforge-dark Monaco editor theme that matches AlgoForge's design system. The editor background now matches the app's #141414 deep dark, keywords use #a088ff (purple accent), strings use #63e3ff (cyan accent), and comments are muted gray. The light theme toggle continues to work correctly.

📝 Walkthrough

Walkthrough

ProblemWorkspace.tsx now defines and registers a custom algoforge-dark Monaco theme, uses it as the default editor theme, and updates the toggle so the editor switches between algoforge-dark and light.

Changes

Custom Monaco Theme Integration

Layer / File(s)	Summary
Theme definition and registration app/src/sections/ProblemWorkspace.tsx	Adds the Monaco imports, defines ALGOFORGE_DARK_THEME with token and UI color overrides, updates the default theme state to algoforge-dark, and registers the custom theme in handleBeforeMount.
Editor props and toggle wiring app/src/sections/ProblemWorkspace.tsx	Wires the Editor to use the theme state and beforeMount callback, and updates the theme toggle button to switch between algoforge-dark and light with accessibility props and icon changes.

Poem

🐇 I hopped through code on midnight paws,
With purple sparks and cyan applause.
Dark theme snug, all bright and neat,
Light still flips on with a single beet! 🥕

In `@app/src/sections/ProblemWorkspace.tsx`:
- Around line 293-299: The icon-only theme toggle in ProblemWorkspace should
expose a proper accessible name instead of relying on title alone. Update the
button that calls setTheme in ProblemWorkspace to include an aria-label
describing the action (for example, toggle theme) and add aria-pressed to
reflect whether the current theme is active; keep the existing icon swap logic
intact so the control remains understandable to screen readers.

Thanks for adding the labels! Heads up on the Vercel deployment failure — it's not a code issue. The Vercel bot is blocking on team authorization:

"Someone is attempting to deploy a commit to the rishabhjtripathi2903-3434's projects Team on Vercel. A member of the Team first needs to authorize it."

To unblock the deploy, the team owner just needs to visit the auth link below once and click Authorize — Vercel will then auto-retry and the build can run:

https://vercel.com/git/authorize?team=rishabhjtripathi2903-3434%27s%20projects&slug=rishabhjtripathi2903-3434s-projects&teamId=team_jHqtB8zMpwhIcOTq8Ah11wb8

Once authorized, the build can run and any genuine build error (if any) will surface in the bot's output. CI / Lint & Type Check passed cleanly on this PR ✅ and codereview is approved ✅.
