v0.7.62

• Merge upstream: ACP SDK 2.5.0; checklist plans from update_plan are items plan_updates with planId codex-structured-plan; fast mode sends the fast service tier (Codex reports it back as priority, which still reads as fast).
• Follow upstream where the fork duplicated it. Session titles in the list and in history are normalized as upstream normalizes them (whitespace collapsed, 256 characters) instead of the first line cut at 120. A custom permission profile resolves to the mode upstream picks from the allowed list. Fork lineage pages through upstream's history paging, with its timeout. _codex/skills_list omits the skills the adapter disables.
• Removed: capabilities._meta.codex.rename. The exported client reads rename support from the standard capabilities.session.title; hasRename and codexExtensionCapabilities(agent).rename keep their meaning.
• Changing systemPrompt on session/resume works again. Since 0.7.60 the app-server unloads a detached thread at once and refuses a resume while it closes; the adapter now waits for the unload before it resumes.
• Source formatting follows upstream throughout. No behavior change.
