Note

Replace millisecond number constants with Duration values and add schema-based Windows process parsing

• Replaces numeric timeout constants with Duration values in both tailscale.ts and ProcessDiagnostics.ts, and updates all Effect.timeoutOption calls accordingly.
• Adds a WindowsProcessRecord schema to ProcessDiagnostics.ts with decodeWindowsProcessJson/decodeWindowsProcessRecord helpers; parseWindowsProcessRows now uses schema decoding and is exported.
• Converts TailscaleCommandError, TailscaleStatusParseError, and TailscaleUnavailableError from Data.TaggedError to Schema.TaggedErrorClass with typed field schemas.
• Risk: probeTailscaleHttpsEndpoint callers must now pass timeout: Duration.Duration instead of timeoutMs: number; passing timeoutMs is silently ignored and the default timeout applies.
