## Title

    [Continue.dev] 'fetch failed' with 'unable to verify the first certificate' / 'self signed certificate in certificate chain' for self-hosted or proxied model endpoints

## Body

    Cause (Documented platform behavior): Documented: certificate chain can't be verified by the extension.
    
    Fix status: documented_behavior
    
    Misleading approaches:
    - Leaving requestOptions.verifySsl: false permanently
    
    Other error fragments:
    - unable to verify the first certificate
    - self signed certificate in certificate chain
    - CERT_UNTRUSTED
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/continuedev/continue/main/docs/troubleshooting.mdx (official_docs, unknown, documented_behavior): Doc lists these TLS errors, recommends requestOptions.caBundlePath, OpenSSL diagnosis steps, win-ca as less reliable alternative, and warns against leaving verifySsl false.
    
    Search phrasings: continue dev self signed certificate in certificate chain; continue fetch failed unable to verify the first certificate; continue caBundlePath
    
    Evidence basis (self-declared by the contributing chat client): public_source.
