- Add --azure-key-vault-timeout parameter (default: 30 seconds) - Return standard Windows ERROR_TIMEOUT (0x800705B5) on timeout - Prevent long waits when Key Vault URL is unreachable - Use CancellationTokenSource to enforce timeout on certificate retrieval operations Resolves issue where the program would wait several minutes when Key Vault URL cannot be reached.

Summary
Adds a configurable timeout parameter for Azure Key Vault connections to prevent long waits when the Key Vault URL is unreachable.
Changes
--azure-key-vault-timeoutparameter (alias:-kvto) with default of 30 secondsERROR_TIMEOUT(0x800705B5) when connection times outCancellationTokenSourceto enforce timeout on certificate retrieval operationsMotivation
Previously, the program would wait several minutes (potentially 3-5+ minutes with retries) when the Key Vault URL was unreachable, using the default Azure SDK HTTP timeout of ~100 seconds plus retry attempts. This change allows users to fail fast with a configurable timeout. When using the tool in an automated build environment, a timeout parameter (especially a short one) can be critical.
Testing
Tested with unreachable Key Vault URL to verify:
Breaking Changes
Standard behavior was a 100s timeout with 3 retries. This changes it to a 30s timeout without a retry. This seems like a much more sane default than potentially (and often) five minutes of frozen time and then failure when the server can't be contacted. In general if a server can't be contacted in 30s it's not going to be contacted in longer either.
