Add initIn for scoped initialization/reinitialization and fix select reinit issues

[correiarmjoao]

Adds scoped initialization via initIn allowing for scoped reinitialization instead of full initialization with init/initAll.
It also fixes a couple of select reinit problems.

• Reinitializing selects no longer crashes when redefining the public value property
• Existing listeners are cleaned up before rebinding so repeated initAll() calls do not leave selects in a broken state

Checked manually:

• normal auto-init still works
• initIn() works on a scoped subtree
• component-filtered init works
• initAll() no longer breaks multiple selects
• forced select reinit still keeps the public API working

I'm actually working on this right now for command, select and combobox.

@hunvreus any idea on ETA? 🙇🏻‍♂️

I'm working on 1.0.0 (close to finished). New docs are here: https://basecoat.hunvreus.workers.dev/components/select/#javascript-api

I added a refresh() methods for some of the components (tabs, command, select, etc). Let me know if that solves your issue.
