fix(conceal): reveal cursor line in normal mode for natural navigation

concealcursor=nc kept the cursor's own line concealed in normal mode, so
the hidden characters of a wikilink ([[, target, ]]) still occupied buffer
columns — each l/h moved one hidden position with no visible movement,
making the cursor feel stuck. Drop the `n` flag (keep `c` for incsearch) so
the cursor line shows raw markup in normal mode while other lines stay
concealed.
