feat(commands): add :Preview open subcommand
Problem: after closing a viewer, there was no way to re-open the last
compiled output without recompiling.

Solution: track the most recent output file per buffer in a `last_output`
table that persists after compilation finishes. Add `compiler.open()`,
`M.open()`, and wire it into the command dispatch.
