Status bar CTX indicator stuck / not incrementing during long sessions (regression)

Summary

The CTX usage indicator in the Claude Code status bar (e.g. CTX:░░░░░░░░ 6%) appears broken after a recent update. The bar does not increment during long sessions — even after heavy tool use, extended thinking (xhigh/max effort), and large input processing, the displayed value stays near its initial low value.

Impact

• Users can no longer judge session CTX usage from the status bar
• Critical signal for managing context in multi-agent / long-running workflows
• Combined with xhigh/max effort occasionally producing 10+ minute stalls, users have no visual way to anticipate context limits

Environment

• Claude Code v2.1.114
• Model: Opus 4.7 (1M context)
• Effort: xhigh / max
• OS: Darwin arm64 (macOS)

Reproduction

1. Start a long-running session with xhigh or max effort
2. Execute many tool calls (Read, Bash, Edit) — especially large file reads
3. Observe status bar: CTX bar stays ~6% despite heavy context accumulation

Expected (Restoration Request)

1. CTX bar progressively fills as tokens accumulate (prior behavior)
2. Visual indication at meaningful thresholds (50% / 30% / 15%)
3. Usage limit / rate-limit indicators reflect actual session state

Additional Context

This regression affects multi-agent orchestration setups (cmux / tmux) where accurate per-surface CTX monitoring is critical for handover timing decisions. Restoring the previous limit display would significantly improve operational reliability.
