Add an account limit meter to the chat composer

[Arimodu]

What Changed

Added a small UI element using the same UI as the context remaining display (just using different color). With a hover tooltip for details
As it is now, this is codex-only. I didn't look into implementing into other harnesses because I don't have an active sub on those.

Why

This is a useful way to see the account limits at a glance (instead of having to open a terminal, run codex, type /status). Courtesy of @iPixelGalaxy for bullying me into using my codex subscription to make this

UI Changes

A table just to make this look nicer

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes

Note

Medium Risk
Adds a new cross-layer runtime event and normalization schema for account rate limits, plus new UI driven off activity ingestion; mistakes could cause missing/incorrect limits or extra event noise but does not touch auth or persistence.

Overview
Adds end-to-end support for displaying account rate limits in the chat composer.

On the server, Codex now proactively fetches account/rateLimits/read on session start and after turn/completed/account/updated, emitting account/rateLimits/updated; provider adapters (Codex + Claude) attach a new normalized snapshot to account.rate-limits.updated, and orchestration ingestion converts that into an account-rate-limits.updated thread activity.

On the web, introduces AccountLimitMeter and wires it into ChatComposer, deriving the latest limit snapshot from activities and hiding these activities from the work log.

Note

Add an account limit meter to the chat composer

• Adds a circular meter UI (AccountLimitMeter.tsx) to the chat composer footer that displays current account rate-limit usage with a popover showing session/weekly reset windows.
• Introduces a normalizeAccountRateLimits utility (packages/shared/src/accountLimits.ts) that parses provider-specific rate-limit payloads into a consistent AccountRateLimitsSnapshot, selecting the most constrained window.
• Refreshes rate limits on session start, turn completion, and account/updated notifications via a new refreshRateLimits method in CodexAppServerManager.ts; failures are non-fatal and logged at debug level.
• Both the Codex and Claude adapters now attach a normalized snapshot to account.rate-limits.updated runtime events, which the ingestion layer converts to account-rate-limits.updated activities.
• Filters account-rate-limits.updated activities out of work log entries in session-logic.ts.

Approvability

Verdict: Needs human review

This PR introduces a new user-facing feature (account limit meter) spanning backend adapters, contracts, shared utilities, and frontend components across 10 files. Additionally, an unresolved review comment identifies a medium-severity bug where the meter may display misleading information when the secondary rate limit window is more constrained than the primary.

This is an older account-usage meter implementation that overlaps active #1732 and the current rate-limit event plumbing. Consolidating on one implementation will avoid duplicate UI and protocol work.
