test(e2e): update composer selectors for new placeholder + voice button

[graycyrus]

Summary

Follow-up to #3165 (composer redesign). That PR renamed the composer placeholder (Type a message... → How can I help you today?) and the mic-entry button (Start recording → Voice mode), and updated the Vitest tests — but the Playwright + WDIO E2E specs that select by those strings were missed and merged stale.

This updates all 26 affected spec files so the E2E specs match the shipped composer:

• getByPlaceholder('Type a message...') → getByPlaceholder('How can I help you today?')
• textarea[placeholder="Type a message..."] selector + harness docstring
• marker-array / textExists / waitForAnyText references
• mic-entry button: Start recording → Voice mode (MicComposer's own record button stays Start recording)

Test plan

• No stale Type a message references remain in app/test/
• All 26 spec files reference the shipped placeholder
• pnpm typecheck — clean
• pnpm format:check — clean
• N/A: No app/Rust changes — test-only follow-up

📝 Walkthrough

Walkthrough

This PR updates test selectors across the E2E and Playwright test suites to match a chat composer UI redesign. The core selector constant in the shared harness helper is updated first, followed by widespread updates to all test specs to use the new placeholder text "How can I help you today?" instead of "Type a message...".

Changes

Chat Composer Placeholder Migration

Layer / File(s)	Summary
Harness helper baseline app/test/e2e/helpers/chat-harness.ts	The shared COMPOSER_SELECTOR constant and its documentation are updated to locate the textarea via the new placeholder text, which affects all E2E tests that use typeIntoComposer or clickSend.
E2E test specs update app/test/e2e/specs/chat-harness-cancel.spec.ts, app/test/e2e/specs/chat-harness-send-stream.spec.ts, app/test/e2e/specs/chat-tool-error-recovery.spec.ts, app/test/e2e/specs/composio-github-tools-tags.spec.ts, app/test/e2e/specs/conversations-web-channel-flow.spec.ts, app/test/e2e/specs/harness-composio-tool-flow.spec.ts, app/test/e2e/specs/skill-multi-round.spec.ts, app/test/e2e/specs/voice-mode.spec.ts	E2E test files update textarea selectors and UI readiness checks to detect the composer by the new placeholder text across cancel, stream, error recovery, tool flow, navigation, and voice mode scenarios.
Playwright test specs update app/test/playwright/specs/chat-conversation-history.spec.ts, app/test/playwright/specs/chat-harness-cancel.spec.ts, app/test/playwright/specs/chat-harness-scroll-render.spec.ts, app/test/playwright/specs/chat-harness-send-stream.spec.ts, app/test/playwright/specs/chat-harness-subagent.spec.ts, app/test/playwright/specs/chat-harness-wallet-flow.spec.ts, app/test/playwright/specs/chat-multi-tool-round.spec.ts, app/test/playwright/specs/chat-tool-call-flow.spec.ts, app/test/playwright/specs/chat-tool-error-recovery.spec.ts, app/test/playwright/specs/conversations-web-channel-flow.spec.ts, app/test/playwright/specs/harness-channel-bridge-flow.spec.ts, app/test/playwright/specs/harness-composio-tool-flow.spec.ts, app/test/playwright/specs/harness-cron-prompt-flow.spec.ts, app/test/playwright/specs/harness-search-tool-flow.spec.ts, app/test/playwright/specs/skill-multi-round.spec.ts, app/test/playwright/specs/user-journey-full-task.spec.ts, app/test/playwright/specs/voice-mode.spec.ts	Playwright test files update all sendMessage helpers and UI readiness assertions to target the chat input using the new placeholder text across conversation, tool flow, error recovery, channel, and voice mode tests.

Possibly related PRs

• tinyhumansai/openhuman#3165: The main PR's test updates to locate the chat composer textarea by the new placeholder ("How can I help you today?") are directly driven by the composer redesign in #3165 that changed the composer's placeholder/UI.
• tinyhumansai/openhuman#2353: Both PRs touch the chat-harness composer typing/sending flow in app/test/e2e/helpers/chat-harness.ts—the main PR changes the textarea locator via the placeholder, while the retrieved PR refactors the composer/send helpers (and adds socket-connected waiting)—so they're code-level related to the same interaction code.

🐰 Selectors dance in the test parade,
"How can I help you?" the new cascade,
From type to talk, the placeholders sway,
Thirty specs updated—hooray, hooray! 🎉
