fix(e2e): align hosted-search version assertion with Pi 1.0.1

[shabhui]

What happened

PR #1357 upgraded the Pi kernel packages to 1.0.1 (workspace pins, patches, lockfile, check scripts) but missed one file: scripts/e2e-hosted-search.mjs still asserts manifest.version === "1.0.0" for pi-ai / pi-agent-core / pi-coding-agent.

Steps to reproduce

1. On current main, install dependencies (Pi 1.0.1 is locked).
2. Run the hosted-search e2e (node scripts/e2e-hosted-search.mjs).
3. The dependency version check fails before any scenario runs:

pi-ai must match the locked pi version

Expected

The e2e tracks the locked Pi version (now 1.0.1) and proceeds past the dependency check.

Actual

Assertion manifest.version === "1.0.0" fails against installed 1.0.1 packages (scripts/e2e-hosted-search.mjs:163).

Fix

Single-line change: bump the assertion to "1.0.1".

Verified: on a Pi-1.0.1-locked workspace (identical pins/patches as main via #1357) the version check passes and the run proceeds past dependency verification.

App version: main @ c79b6ca (post #1357)
OS: Windows 11 26220.9587

Thanks for catching the stale Pi version assertion after #1357. The follow-up in #1375 now derives the expected version from the exact agent-runtime pin and fixes the offline host fixture for session.appendMessage; its 7 hosted-search scenarios and CI passed. Closing this original as superseded.
