[FEATURE] Claude Code mobile/web: show model, context (K), effort level & usage limit

Problem Statement

On the mobile / web Claude Code surface there's no persistent indicator of session
state. You can't tell at a glance which model is active, how full the context is, what
effort level you're on, or how close you are to a plan/rate limit.

This is especially acute when driving a remote session (/rc) from mobile — you're
steering a session you can't fully see, so knowing the model, context fill, effort, and
remaining usage at a glance really matters. But honestly it should just be always
visible, remote session or not.

Proposed Solution

Add an always-visible status readout (header or above the input) showing:

• Model (e.g. Opus 4.8)
• Context size in K (e.g. 42k/200k, %)
• Effort level (e.g. high / max)
• Usage / limit (session + weekly, shared across surfaces)

Persistent by default — not behind a tap/menu.

Alternative Solutions

No current way to see this persistently on mobile; usage/limits are buried in menus,
and during a remote session there's even less visibility into what's happening.

Priority

High - Significant impact on productivity

Other (mobile / web app)

Use Case Example

1. I start a remote session with /rc and continue it from my phone.
2. Mid-session I want to send a large prompt but don't know how full the context is or

how close I am to my weekly limit.

1. A persistent header (Opus 4.8 . 120k/200k . effort: max . weekly 16%) tells me

instantly — so I can compact, switch model, or hold off, without opening any menu.
