fix(compiler): guard active entry before clearing in process callback

Browse source 
Problem: when M.compile() is called while a previous process is still
running, the old process's vim.schedule_wrap callback unconditionally
sets active[bufnr] = nil, wiping the new process from the tracking
table. status() incorrectly returns idle and stop() becomes a no-op
against the still-running process.

Solution: capture obj as an upvalue in each callback and only clear
active[bufnr] if it still points to the same process object.
