keybindings.json user customization disabled when DISABLE_TELEMETRY=1

Bug Report

Summary

User keybinding customization (~/.claude/keybindings.json) is silently ignored when DISABLE_TELEMETRY=1 is set in settings.json. The debug log reports Skipping file watcher - user customization disabled on every session start, and custom keybindings have no effect.

Steps to Reproduce

1. Add "DISABLE_TELEMETRY": 1 to ~/.claude/settings.json under "env"
2. Create a valid ~/.claude/keybindings.json with custom bindings
3. Start a new Claude Code session
4. Custom keybindings do not work

Debug Log Output

Every session start shows:

[keybindings] KeybindingSetup initialized with 104 bindings, 0 warnings
[keybindings] Skipping file watcher - user customization disabled

Root Cause (suspected)

The keybinding customization feature is gated behind the tengu_keybinding_customization_release GrowthBook feature flag. When DISABLE_TELEMETRY=1 is set, GrowthBook cannot initialize and the flag evaluates to false — even though a cached value of true exists in ~/.claude/.claude.json. The code then skips loading keybindings.json entirely.

The fix should be to either:

• Fall back to the cached feature flag value when network traffic is disabled, or
• Not gate a local filesystem feature like keybinding customization behind a network-fetched feature flag at all

Expected Behavior

DISABLE_TELEMETRY should not affect local filesystem features like keybinding customization.

Workaround

Remove DISABLE_TELEMETRY: 1 from settings.json.
