Greptile Summary

This PR fixes two independent issues: (1) Telegram API requests that surface as grammY "Network request for '...' failed[!]" / "failed after N attempts." errors were not being retried in the send context — a new dedicated regex (GRAMMY_NETWORK_REQUEST_FAILED_RE) is added and checked before the allowMessageMatch guard so these errors are always classified as recoverable regardless of context. (2) On Windows with Bun (which doesn't ship npm-cli.js next to process.execPath), resolveNpmArgvForWindows was returning null and falling through to a plain command resolution that could trigger spawn EINVAL; the fix falls back to npm.cmd/npx.cmd, which are then detected by isWindowsBatchCommand and correctly routed through cmd.exe.

Key changes:

• src/telegram/network-errors.ts: New GRAMMY_NETWORK_REQUEST_FAILED_RE regex added; matched before the allowMessageMatch guard so grammY envelope errors are retried even in send context.
• src/process/exec.ts: resolveNpmArgvForWindows now falls back to npm.cmd shim when npm-cli.js is not found, ensuring Windows + Bun spawns are routed through cmd.exe correctly.
• Tests are appropriately added for both changes; the existing "skips broad message matches for send context" test was correctly updated to use a "timed out" variant that still exercises the allowMessageMatch guard.

No issues found. Both fixes are narrow, well-tested, and the logic in each path is correct.

Confidence Score: 5/5

• This PR is safe to merge — both fixes are narrow, well-tested, and logically sound.
• The regex change is precise and cannot accidentally match non-network errors. The Windows/Bun fallback correctly routes through cmd.exe via the existing isWindowsBatchCommand guard. New tests directly exercise both code paths.
• No files require special attention.
