Greptile Summary

This PR fixes a UTF-8 encoding issue on Windows by prepending chcp 65001>nul to the generated gateway task scripts, enabling cmd.exe to correctly handle non-ASCII characters (e.g., Chinese) in paths, environment variables, and arguments. A companion change teaches readScheduledTaskCommand to skip this bootstrap line during parsing, maintaining round-trip fidelity. Tests are added to cover both sides: script generation with Chinese-character paths and parser skipping of the bootstrap line.

Changes:

• schtasks.ts: buildTaskScript now initialises lines with ["@echo off", "chcp 65001>nul"]; new isCmdUtf8BootstrapLine regex helper (case-insensitive, handles optional @ prefix, .com/.exe extension, and >nul redirect) is wired into readScheduledTaskCommand to skip the line during parsing.
• schtasks.install.test.ts: Existing test gets a toContain("chcp 65001>nul") assertion; new end-to-end test covers a full install + read-back cycle with Chinese-character paths and environment variables.
• schtasks.test.ts: New unit test directly exercises readScheduledTaskCommand with a script that includes the bootstrap line, verifying it is skipped correctly.

Confidence Score: 5/5

• This PR is safe to merge — the change is minimal, well-scoped, and thoroughly tested.
• The implementation is a targeted two-line change to script generation and a corresponding parser guard. The regex in isCmdUtf8BootstrapLine is correct and not susceptible to ReDoS. Tests cover generation ordering (CRLF), round-trip parsing, and the parser-only path with a Chinese-character fixture. No existing behaviour is broken.
• No files require special attention.
