Walkthrough

Implements lazy loading of pioarduino-node-helpers and deferred installer stage initialization, adjusts installer check/install flow and teardown, ensures Windows terminals set UTF-8 on creation, updates a docs platform-zip URL, and bumps package version and two dependencies.

Changes

Cohort / File(s)	Summary
Docs asset update assets/welcome/pioarduino-ini-example.md	Replaced env.platform URL from a specific 51.03.04 release zip to the stable release zip.
Versioning & dependencies package.json	Bumped version 1.0.6 → 1.0.7; updated dependencies.pioarduino-node-helpers ~11.3.4 → ~11.4.0; updated devDependencies.eslint-plugin-import ~2.31.0 → ^2.32.0.
Installer lazy init & lifecycle src/installer/manager.js	Deferred stage construction (this.stages = null), added createStages() which dynamically requires pioarduino-node-helpers, ensured check() and install() call createStages(), made destroy() defensive and clears stages.
Extension runtime lazy-loading src/main.js, src/utils.js	Replaced top-level static import of pioarduino-node-helpers with on-demand require calls in functions (patchOSEnviron, startInstaller/startPIOHome, handleUseDevelopmentPIOCoreConfiguration, notifyError, listCoreSerialPorts); startInstaller logs a warning and returns false on check error.
Terminal UTF-8 initialization src/terminal.js	PIOTerminal now initializes terminal in a local var and explicitly sends chcp 65001 on Windows when creating or recreating the terminal before sending further text; public API unchanged.

Poem

A rabbit taps keys with a whiskered grin,
Lazy modules hop in when the work should begin.
Stages wake on call, terminals sing UTF-8,
Installer sighs safe, no surprise on update.
Version bumped, carrots stacked—hop to a cleaner state! 🥕🐇
