[codex] Add Hugging Face hosted links to README

[kiankyars]

Summary

Add a short top-level section to the README that points people to the hosted Hugging Face entry points for ML Intern.

What Changed

• added a Try It on Hugging Face section near the top of the README
• linked the ML intern explorers org
• linked the hosted smolagents/ml-intern Space

Why

The repo README explained the local CLI flow, but it did not surface the main hosted Hub entry points that Hugging Face is promoting publicly.

Validation

• docs-only change
• no tests run

@claude please review this PR. Focus on correctness, security, LiteLLM/Bedrock routing impact, and whether it's safe to merge against current main. Keep it concise and prefer inline comments where it matters.

Verdict: ✅ Safe to merge — docs-only, no code changes.

Correctness

The added section (README.md lines 9–14) is straightforward and accurate per the PR description. Two minor nits:

1. URL validity — neither https://huggingface.co/ml-agent-explorers nor https://huggingface.co/spaces/smolagents/ml-intern can be verified from this review. A broken link here is the first thing a new user sees. Please confirm both are publicly accessible before merging.

2. Capitalization inconsistency — display text says ML intern explorers (lowercase i), but the project is consistently styled ML Intern (capital I) everywhere else in the README. Fix this →

Security

None. No credentials, tokens, or secrets introduced. Pure markdown.

LiteLLM / Bedrock routing impact

None. Only README.md is touched — zero routing code changes.

Merge safety against current main

Clean. The diff applies to the top of the file with no overlap with any in-flight code changes. No merge conflicts expected.

Pre-merge checklist (for the author):

• Confirm huggingface.co/ml-agent-explorers is publicly accessible
• Confirm huggingface.co/spaces/smolagents/ml-intern is publicly accessible
• Optionally fix the ML intern → ML Intern capitalization
