fix(chat): show tool identity in work logs

[Gigioxx]

What Changed

Work-log rows could say Tool or Tool updated even when provider metadata identified the operation. Reuse the shared tool presentation helper to derive missing titles and bounded targets before payload trimming, including historical rows. Both clients fall back to retained metadata, and mobile expanded commands keep labels such as Running ps instead of Command.

Closes #11903.

Why

Tool identity belongs in the existing shared presentation path. This preserves useful titles and error details and reuses the current same-call lifecycle collapse.

Verification

• Reproduced before the fix: the mobile feed test returned Tool updated instead of Read file; isolated Chromium showed three Tool rows beside a command.
• 330 focused tests passed across mobile, web, shared presentation, projection, and ACP normalization. Additional Grok and Antigravity adapter tests passed.
• Web, mobile, and server typechecks passed. Targeted lint and formatting passed.
• After rebase onto current main, the same browser fixtures show the file path, search query, GitHub tool name, and command. Expansion exposes retained details. A browser with old cached payloads also recovered tool names through the client fallback.
• Claude Opus and independent Codex reviews found no blocking issues. Added the suggested shared-fallback coverage and checked ACP callers.
• Native iOS/Android was not exercised: this Linux host has no native simulator tooling. Mobile behavior is covered by its actual feed/presentation tests; screenshots below are the web client, shared with desktop.

Summary by CodeRabbit

• Improvements
  • Activity entries now show clearer tool names and summaries for file reads, edits, searches, and commands.
  • Tool identity and readable labels remain consistent across ongoing, completed, and sparse updates.
  • Command labels provide more informative running and completed states.
  • Search summaries distinguish web searches from file searches and include relevant queries.
  • Long file paths in activity details are shortened for improved readability.

Approvability

Verdict: Approved at 852c607

Macroscope's review found this PR approvable — This is a bounded work-log presentation fix that derives missing tool identity before payload slimming and updates the web/mobile labels without changing schemas, workflows, or product defaults. Regression tests cover sparse lifecycle updates, server projection, truncation, and command-status rendering.

📝 Walkthrough

Walkthrough

Shared tool presentation now infers specific titles and details from sparse lifecycle payloads. Server projection, web work logs, and mobile work logs use these results. Tests cover tool shapes, truncation, command labels, and lifecycle updates.

Changes

Tool activity presentation

Layer / File(s)	Summary
Shared tool metadata inference packages/shared/src/toolActivity.ts, packages/shared/src/toolActivity.test.ts	Tool metadata extraction now recognizes additional command, path, action, title, nested argument, and search-input shapes. Generic labels are filtered before specific tool summaries are derived.
Projection and runtime presentation apps/server/src/orchestration/ActivityPayloadProjection.ts, apps/server/src/orchestration/ActivityPayloadProjection.test.ts, packages/client-runtime/src/work-log/toolPresentation.ts, packages/client-runtime/src/work-log/toolPresentation.test.ts	Server projection and client-runtime extraction infer bounded titles and details for tool lifecycle payloads. Existing titles and details remain unchanged, and sparse updates retain tool identity.
Work-log integration apps/web/src/session-logic.ts, apps/mobile/src/lib/threadActivity.ts, apps/mobile/src/lib/threadActivity.test.ts	Web and mobile work-log entries use shared tool presentation results. Command rows use running or completed labels with the detected program. Mobile tests cover stable Read file identity and command lifecycle labels.
