overhaul:

- use TOML files to define content
- `roxy_lbl()`: add logical param `as_sentence` which defaults to `TRUE`; if `FALSE`, result begins lower-case and omits final punctuation
- improve doc
- remove long-form fn aliases (`*_label*()`, `abbreviations()`)
- move only R condition message to MD snips and remove all msg stuff
- rename param / colname `name` to `id` in all relevant places
- properly define set of supported roxy tags for lbls
- tweak roxy lbl IDs
- update pkg title
- update TODOs
