squad watch silently ignores --monitor-teams and other flags; Teams webhook not implemented #739

Summary

Running squad watch with notification flags (--monitor-teams, --monitor-email, --execute, --board, --two-pass, --retro, --decision-hygiene, --wave-dispatch) has no effect — the flags are silently ignored and no Teams/email messages are ever sent.

Root Cause

Two separate issues:

1. CLI entry point drops all flags except --interval

In cli-entry.ts (lines 322–329), the watch command parser only extracts --interval:

if (cmd === 'triage' || cmd === 'watch') {
  const { runWatch } = await import('./cli/commands/watch.js');
  const intervalIdx = args.indexOf('--interval');
  const intervalMinutes = (intervalIdx !== -1 && args[intervalIdx + 1])
    ? parseInt(args[intervalIdx + 1]!, 10)
    : 10;
  await runWatch(process.cwd(), intervalMinutes);
  return;
}

All other flags are never read, never passed to runWatch(), and never surface any warning.

2. Teams webhook adapter is not implemented

In squad-sdk/src/platform/comms.ts (lines 103–106), the teams-webhook channel falls back to file logging:

case 'teams-webhook':
  console.warn('Teams webhook adapter not yet implemented — using file log fallback');
  return new FileLogCommunicationAdapter(repoRoot);

Even if the CLI parsed --monitor-teams, messages would still go to the file log, not Teams.

Reproduction

squad watch --monitor-teams --monitor-email --execute --board --interval 1

Expected: Teams and/or email notifications when board state changes.
Actual: No notifications. Flags are silently ignored. No warning printed.

Suggested Fix

1. Parse all flags in cli-entry.ts and pass them through to runWatch() as an options object.
2. Warn users if unrecognized or unimplemented flags are passed (e.g. ⚠ --monitor-teams is not yet implemented).
3. Implement the Teams webhook adapter — or at minimum surface the "not yet implemented" warning when the flag is explicitly requested.
4. Update runWatch() signature to accept the full set of options.
