A theme that names no tint for its tags' names takes one of its own hues, so every theme draws a file's name, a +Name and the Tty word off the tag's ink

The faithful ports (neobones_dark, dracula, tokyonight, the *bones, ...),
every helix import and any theme file set no tag_name_fg, and ChromeTheme
fell back to the plain ink: their tags lost the accent the pardes themes
have. The user's neobones_dark looked tinted before only because the Sep 24
build had no such theme and fell back to orchard.

The tint is now derived when unset: the theme's keyword colour, else the
first of its ANSI accents, syntax, grip, selection or diagnostic colours
with a hue, placed at the lightness nearest the ink where the hue holds,
at least 4.5:1 on its ground (half a point under the ink's own where the
ink has less to spare) and 0.07 off the ink in OKLab. Each ground, plain and
focused, gets its own. A theme that names its tint keeps it exactly.

Tests: every theme's chrome keeps both tints off the ink and legible; every
theme draws a file's basename, +Errors and Tty+sh in a tint, focused or not.
