Add autocompleteBraces behavior setting

Adds a new 'autocompleteBraces' option to the Behavior configuration that
controls whether opening brackets automatically insert their closing pair.

When disabled, typing '{' will only insert '{' without the automatic '}'.

This enables downstream editors like CodeEdit to respect user preferences
for bracket auto-completion.

Changes:
- Add autocompleteBraces property to Behavior struct (default: true)
- Conditionally set up OpenPairFilter and DeletePairFilter based on setting
- Trigger setUpTextFormation when setting changes
