Slow auto-expand project item clicks

[qqrm]

Motivation

• Auto-expanding project folders was triggering many clicks in quick succession which can confuse the UI/React, so clicks should be staggered to better mimic human interaction.
• The extension version must be bumped when changing logic so deployments remain consistent.

Description

• Added AUTO_EXPAND_PROJECT_ITEM_CLICK_DELAY_MS = 500 and a per-item delayMs counter to stagger folder toggle clicks.
• Replaced immediate dispatchHumanClick calls with window.setTimeout scheduling and updated the debug message to include the scheduled delay.
• Bumped manifest.json version from 1.0.104 to 1.0.105.

Testing

• Ran npm run lint which completed successfully.
• Ran npm run format:check and npm run format:write and confirmed prettier formatting passed.
• Ran npm run typecheck and npm run test where vitest reported 1 test passed.
• Ran npm run verify which completed successfully.
