fix(buffer): replace indentexpr with dedicated o/O mappings

Browse source 
Problem: setup_indentexpr always returned 0 because no task line
starts with whitespace (the /ID/ prefix begins with /), so the
return 2 branch was dead code. Pressing o or O opened a blank line
at column 0 with no ID prefix, which the diff parser cannot
recognise as a task.

Solution: remove setup_indentexpr and M.get_indent() entirely; add
M.open_line(above) which inserts a two-space stub line and enters
insert mode at the end so the user types directly into the new task
body. The diff layer already handles lines matching ^  .+ as new
tasks. Add o and O buffer-local mappings in init.lua.
