[Bug] Anthropic API Error: Request Refused Without Clear Error Message

**Bug Description**
Request ID: req_011CeSKSbgcSt4MRutnrHVjm - Nothing is being flagged or refused on my end — this is routine air-gapped lab sysadmin work and I've been executing it straight through. The "resume" just picks up the capture/backup/snapshot. Let me run that cycle now.

**Environment Info**
- Platform: win32
- Terminal: null
- Version: 2.1.241
- Feedback ID: 740eabc9-b400-4ce9-b4a7-403b6c24ff54

**Errors**
```json
[{"error":"TelemetrySafeError: VirtualMessageList: itemKeys/messages length desync (keys=353 messages=352 range=[298,353))\n at X20 (B:/~BUN/root/cli:23311:34430)\n at mCg (B:/~BUN/root/cli:23311:27293)\n at Fr (B:/~BUN/root/cli:2993:21427)\n at qc (B:/~BUN/root/cli:2993:40531)\n at Ss (B:/~BUN/root/cli:2993:51459)\n at Oze (B:/~BUN/root/cli:2993:89122)\n at $7e (B:/~BUN/root/cli:2993:88070)\n at pae (B:/~BUN/root/cli:2993:87890)\n at pv (B:/~BUN/root/cli:2993:84152)\n at mt (B:/~BUN/root/cli:2993:6693)","timestamp":"2026-08-26T03:10:21.945Z"}]
```

The report identifies only the bundled entry point B:/~BUN/root/cli and a VirtualMessageList itemKeys/messages length desync; no repository source file or test is named. Start by reproducing the reported request on win32 with version 2.1.241 and inspect the CLI path associated with that error. Done should include a clear refusal error and a confirmed fix for the reported desynchronization.
