[Bug] Todo tools and /todos command missing in fresh session on v2.1.216

Bug Description
Todo/task feature completely absent in a fresh session on 2.1.216 (macOS)

In a fresh session, the entire todo feature is missing: TaskCreate, TaskUpdate, and TodoWrite are not in the model's tool list — not even as deferred tools loadable via ToolSearch — and the /todos slash command does not exist.

Verified:

• Version 2.1.216, macOS (Darwin 25.5.0), native install at ~/.local/share/claude/versions/2.1.216
• The binary does ship the tools — strings finds exact matches for TaskCreate, TaskUpdate, and TodoWrite
• No disabledTools or equivalent in ~/.claude/settings.json or project .claude/settings.local.json
• Fresh session, so this is not a stale-feature-flag issue
• ToolSearch("select:TaskCreate,TodoWrite") returns "No matching deferred tools found"

Expected: the todo tools and /todos available, as in prior versions. The feature is still actively maintained per the changelog (2.1.169, 2.1.208, 2.1.210), so this looks like unintended gating rather than a removal.
