chore: prepare for CRAN resubmission

- Declare R (>= 4.1.0) in DESCRIPTION (the package uses the native
  pipe |> and the lambda shorthand \(x); this was a NOTE in the CRAN
  checks that preceded the 2025-12-13 archival)
- Bump RoxygenNote to 7.3.3
- Record the stringr 1.6.0 fix from #59 in NEWS
- Exclude .claude/ from package builds and git history

 - `convert_jyear()` and `convert_jdate()`: the default of `legacy` is changed from `FALSE` to `TRUE` (#60). The non-legacy ('ICU'-based) path can abort the R process on platforms where `stringi` is linked against system 'ICU' (e.g. macOS), and the failure cannot be caught from R. The legacy path based on `lubridate` is now the default, and the previous behaviour is opt-in via `legacy = FALSE` or `options(zipangu.convert_jyear.legacy = FALSE)` / `options(zipangu.convert_jdate.legacy = FALSE)`.
 
+## Fix
+
+- `separate_address()`: handle `NA` patterns in `stringr::str_remove()` for compatibility with stringr 1.6.0 (@hadley, #59).
+
+## Enhancement
+
+- Declare `R (>= 4.1.0)` in `Depends`, reflecting use of the native pipe `|>` and the lambda shorthand `\(x)`.
