release: v0.1.1 — bug fixes, CSS scoping, parser improvements

Bug Fixes:
- fix(core): insert() replace param was non-functional due to identical ternary branches
- fix(types): correct project URL typo (MetonaToast → MetonaEditor)

Improvements:
- feat(core): scope CSS theme variables to .me-wrapper per-instance, preventing global style pollution
- feat(themes): add optional target parameter to setThemeVariables() for element-scoped theming
- perf(parser): improve bold/strikethrough regex to support inline delimiter chars (e.g. **a*b**, ~~a~b~~)
- fix(parser): prevent *** cross-tag nesting by requiring first content char ≠ delimiter
- docs(animations): clarify module purpose as future-use animation metadata registry

Tests:
- test(core): add 2 cases for insert() replace:true / replace:false behavior
- All 409 tests passing (+2 new)

Chores:
- bump version 0.1.0 → 0.1.1 across all source files, package.json, README, and demo
