Description

The nemoclaw  logs subcommand only implements --follow. Flags --tail N, --since , and --help are silently accepted but ignored — the command returns the full log dump (~200 lines) regardless of any flag passed. No error or warning is shown to indicate the flags have no effect.

Device:        Station
OS:            Ubuntu 24.04.4 (aarch64)
Architecture:  aarch64
OpenShell CLI: 0.0.36
NemoClaw:      v0.0.31

With a running sandbox named "my-assistant":

1. nemoclaw my-assistant logs
   (works, returns full log)

2. nemoclaw my-assistant logs --tail 50
   (expected: last 50 lines; actual: full dump ~180 lines)

3. nemoclaw my-assistant logs --since 5m
   (expected: logs from last 5 minutes; actual: full dump)

4. nemoclaw my-assistant logs --help
   (expected: flag usage printed; actual: full log dump executed)

--tail N   → return only the last N lines
--since T  → return only logs from the last T duration
--help     → print flag usage and exit 0 without fetching logs

All three flags are silently ignored. Full log dump (~180 lines) is returned in all cases.
No error, no warning, no indication that the flags had no effect.

nemoclaw my-assistant logs --follow  ✅ works correctly (streaming)
nemoclaw my-assistant logs --tail 50 ❌ returns full dump, --tail ignored
nemoclaw my-assistant logs --since 5m ❌ returns full dump, --since ignored
nemoclaw my-assistant logs --help    ❌ executes logs instead of showing help

src/nemoclaw.ts — logs handler:
  sandboxLogs(cmd, actionArgs.includes("--follow"));
  Only --follow is checked. All other flags in actionArgs are discarded.

src/nemoclaw.ts — buildSandboxLogsArgs() hardcodes:
  ["logs", sandboxName, "-n", "200", "--source", "all"]
  User-supplied --tail / --since values are never read or forwarded.

src/lib/command-registry.ts — logs command registered with:
  flags: "[--follow]"
  No --tail, --since, or --help flags are defined.

Confirmed via code analysis: src/nemoclaw.ts (logs handler, buildSandboxLogsArgs).
Observed on galaxy-sku2-018 (NemoClaw v0.0.31, Ubuntu 24.04.4 aarch64).
Affects all platforms (CLI parsing issue, not platform-specific).
