v5.3.0

What's Changed

Improvements

• Live effort detection via stdin effort.level (CC 2.1.119+) — the canonical source. The model badge now reflects mid-session /effort changes and correctly displays all levels including max.
• Effort badge is now omitted entirely on models that don't support effort, instead of showing a fallback character.

Display Changes

• model:effort=short now renders L/M/H/X/MAX (was L/M/H/A with first-letter fallback for unknown values).
  • xhigh → X (explicit, was H via fallback)
  • max → MAX (was lowercase max)
  • auto no longer appears — CC always resolves it to a concrete level
• model:effort=full now renders the actual level name including xhigh / max (was low/medium/high/auto).

Removed

• CLAUDE_CODE_EFFORT_LEVEL env var override and settings-file fallback. These were workarounds for a missing upstream feature. No user action required — stdin now provides the live level automatically.
