DT2 0.1.2

Bug fixes

dt2_cols_escape() now actually escapes HTML when escape = TRUE (the default). Previously both escape = TRUE and escape = FALSE produced the same identity renderer, so cell content was always inserted as raw HTML.
Server-side processing: the default request parser used by dt2_ssp_handler() / dt2_bind_server() now URL-decodes query-string keys, so global search and column ordering are applied. Previously only pagination worked, because encoded keys such as search%5Bvalue%5D and order%5B0%5D%5Bcolumn%5D were never matched.

dt2() now fills options$columns from the data when it is not supplied, matching the column list the JavaScript side derives.
Name-based column helpers (dt2_cols_*(), dt2_format_*(), dt2_order(), ...) now emit an informative warning when a column name cannot be resolved (for example when options$columns was not set), instead of silently producing an invalid target.
The number and date/time format helpers build their JavaScript using properly quoted and escaped string literals, fixing broken output when a prefix, suffix, locale or format string contained a quote.
print() for dt2_theme objects now also shows the class field.

Added a test suite (testthat) covering the fixes above.
Added a GitHub Actions R-CMD-check workflow.
Reorganised the pkgdown reference index into thematic sections, added runnable examples to dt2_order(), dt2_search_global(), dt2_use_buttons() and dt2_language(), cross-linked dt2_buttons()/dt2_use_buttons(), and documented the options$columns pattern in the vignettes.
New package logo.
