fix: preserve square brackets and escape quotes in note content (v1.1.1)

- Fix square bracket removal: Remove [] from DANGEROUS_CHARS regex
  * Wikilinks ([[link]]) now work correctly
  * Task checkboxes (- [ ] Task) are properly preserved
  * Brackets are safe because values are quoted and passed as array args

- Fix quote truncation: Escape double quotes in formatParam
  * Content like "Bot QM" no longer truncates
  * Internal quotes escaped as \" before wrapping in parameter quotes
  * Prevents shell from misinterpreting quote boundaries

Bump version: 1.0.0 -> 1.1.1
