Label in-flight transcript activity with present tense

[eivindjonassen]

Summary

Transcript activity labels used past tense from the first streamed byte. Reasoning said THOUGHT before any text existed, an exploration group said Explored while its searches were still running, and a live shell message said Shell. Labels now follow the actual state and settle once the activity ends.

• Reasoning: THINKING / Thinking in flight, THOUGHT / Thought when done. Settled from part time.completed, with the message completion time as a fallback so a REST snapshot that omits part timing cannot strand a finished thought as Thinking.
• Exploration group: Exploring while any tool is running or streaming, Explored otherwise.
• Shell message: Running while status === "running", Ran for every terminal state. Previously timeout and killed fell through to a bare Shell.

Group labels Edited, Ran shell, Used Skill, and Used X needed no change. groupAssistantParts only collapses a run when every tool is completed, and single in-flight tools render plain nouns.

Testing

• pnpm check green: lint, typecheck, 299 tests, iOS and Android Hermes exports.
• New tests cover each flip: reasoning rerender, message-level settlement fallback, exploration group with a running search, and shell running to exited.
• Integration fixture reasoning parts gained time: { created, completed } to match real snapshot shape.

Deploy note

An EAS Update was published from this tree to the preview branch at runtime version 0.1.4 before the branch was cut, so preview builds are already serving this change. Production is untouched.
