Don't truncate commands + show running commands

[Minigamer42]

What Changed

• Removed the manual truncateDetail call for tool calls send by the agent (the output is still truncated via css ellipsis in the UI, but can be viewed by hovering)
• Show the command while it is running with optionally a different label

Why

• Longer commands got truncated in the UI
• Sometimes the agent would run a command in the background and get stuck (like an interactive binary or something that takes very long to complete). Currently the UI gives no feedback on that until the command exits or you kill it via taskmgr or similar.

UI Changes

• State before this PR:

• Longer command string visible:

• Different label while the command is running:

• Same command with formatting:

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
Changes tool lifecycle event payloads and client-side collapsing logic, which could increase event payload size and alter how work-log rows merge/render during active turns.

Overview
Improves tool/command visibility in the timeline by preserving full detail for tool.started/tool.completed events (no server-side truncation) and by attaching itemId to tool lifecycle activity payloads so entries can be reliably correlated end-to-end.

Updates Codex runtime mapping to label command_execution as "Running command" on start, and updates the web work-log derivation to include running command rows while collapsing started/updated/completed events using a stable collapseKey (preferring itemId) so lifecycle rows merge correctly even when events aren’t adjacent.

Note

Show running commands in chat and stop truncating command detail

• tool.started events for command_execution items are now included in the work log (previously all tool.started events were filtered out), displaying a "Running command" title while in progress and "Ran command" on completion.
• Command detail payloads are no longer truncated in tool.started and tool.completed activities in ProviderRuntimeIngestion.ts.
• Collapse logic in session-logic.ts is reworked to group lifecycle entries by collapseKey (preferring itemId) across non-adjacent entries, replacing the previous immediate-predecessor-only approach.
• React keys for work entry rows in MessagesTimeline.tsx now prefer collapseKey over id, which may alter component reuse during updates.
• Behavioral Change: work log entries now retain collapseKey, and tool.started for non-command items remains filtered out.

Approvability

Verdict: Needs human review

This PR modifies runtime behavior for command display (removes truncation, adds 'Running' state indication) with non-trivial changes to work log collapsing logic. An open review comment identifies a potential bug where lifecycle-dependent titles could prevent proper collapsing of started/completed entries when itemId is absent.
