feat: align extension with patchloom CLI v0.7.0

[SebTardif]

Summary

Align the VS Code extension with Patchloom CLI v0.7.0 (release notes).

Changes

CLI argument rename (--to -> --new)

v0.7.0 renamed replace CLI arguments to match LLM priors. The extensions Quick Action replace command now uses --newinstead of--to`.

MCP parameter rename (selector -> key)

v0.7.0 renamed the doc tool MCP parameter from selector back to key. Fixed the managed install e2e test that was failing because of this.

Windows ARM64 managed install

v0.7.0 added pre-built binaries for aarch64-pc-windows-msvc. The managed installer now supports Windows ARM64 devices (Surface Pro X, etc.).

README update

Updated recommended CLI version from 0.6.0 to 0.7.0.
