]f, mif and the other textobject keys use helix's own queries

helix's textobjects.scm for pardes's grammars are vendored in vendor/queries
under MPL-2.0, each with a header naming its source and what it inherits,
inlined; a README says what is there and what is not. syntax.objectAt and
objectNext run them over the file's kept parse, with their #eq? and #match?
predicates, for ]f [f ]t [t ]a [a ]c [c ]T [T ]e [e ]x [x and mi/ma with
f t a c T e x. erlang's and zig's queries do not compile against the grammar
versions pardes builds and are left out; fortran, markdown and powershell
have none in helix. A test replays sixteen Python and JSON cases whose
results were taken from the installed hx, and another holds that every
vendored query compiles.
