The isValidModelId regex required the first character to be alphanumeric, rejecting Cloudflare Workers AI model IDs like @cf/meta/llama-3-8b-instruct. Add '@' to the allowed first character set. Fixes langchain-ai#315

Summary
The isValidModelId regex in src/constants.ts requires the first character to be alphanumeric, which rejects all Cloudflare Workers AI model IDs (e.g. @cf/meta/llama-3-8b-instruct). This makes Workers AI unusable as an openai-compatible backend.
Fix
One-character change to the regex — add @ to the allowed first character set:
