[BUG] Slash commands `/remote-control`, `/rc`, `/btw` not available for Team plan `primary_owner` - CLI `claude remote-control` works

What's Wrong?

On a Team plan, the primary_owner of the organization does not see plan-gated slash commands (/remote-control, /rc, /btw) inside an active session, while other team members on the same subscription do.

The CLI command claude remote-control works correctly — only the in-session slash commands are missing.

After a full reinstall (native → Homebrew) and fresh login (deleted ~/.claude.json, re-authenticated via OAuth), the hasAvailableSubscription field is never written to ~/.claude.json. Team members with organizationRole: "member" reportedly have this field set to true.

What Should Happen?

• /remote-control, /rc, and /btw should be available as slash commands inside an active session
• hasAvailableSubscription should be set to true after OAuth login for a primary_owner on a Team plan
• The primary_owner should have at least the same feature access as regular team members

Steps to Reproduce

1. Be the primary_owner of a Team plan organization
2. Install Claude Code via Homebrew (brew install --cask claude-code)
3. Run claude and authenticate via /login (OAuth through claude.ai)
4. Open a session and type / to see available commands
5. /remote-control, /rc, and /btw are missing from the list
6. Exit and run claude remote-control from the terminal — this works correctly
7. Inspect ~/.claude.json — hasAvailableSubscription is absent

Additional Information

Relevant ~/.claude.json fields

{
  "oauthAccount": {
    "emailAddress": "",
    "organizationRole": "primary_owner",
    "billingType": "stripe_subscription",
    "hasExtraUsageEnabled": false
  },
  "cachedExtraUsageDisabledReason": "org_level_disabled",
  "penguinModeOrgEnabled": false
}

Note: hasAvailableSubscription is completely absent — not false, just missing. Other team members (organizationRole: "member") on the same org reportedly have hasAvailableSubscription: true.

Environment

• Claude Code version: 2.1.72
• Install method: Homebrew (previously native — fully cleaned up, no leftover files in ~/.local/)
• OS: macOS
• Auth method: OAuth (claude.ai)
• Plan: Team (stripe_subscription)
• Organization role: primary_owner

Additional Context

• A full reinstall cycle was performed: uninstalled native, removed ~/.local/share/claude and ~/.local/bin/claude, installed via Homebrew, deleted ~/.claude.json, re-authenticated — issue persists
• The CLI command claude remote-control works, suggesting the server-side entitlement is correct but the client-side slash command visibility check is failing
• Possibly related to #28322, #33119, and #28773, but distinct because those don't identify the primary_owner role as the root cause
