runtime(context): fix issue with SyncTeX and update command

runtime(context): fix issue with SyncTeX and update command

Remove `--nonstopmode` because (a) ConTeXt always stops anyway, and (b)
`--nonstopmode` disables SyncTeX unconditionally. Add `--paranoid`,
which prevents the command to descend to `..` and `../..`.

Pass the typesetting command only the name of the input file rather than
its full path, as that is more compatible with ConTeXt's syncing
mechanism.

closes: #19323
