docs(v0.8): re-home the auto_sync runtime to v0.8

v0.7 closed with manual :gl/:gp only, leaving the auto_sync timer
unscheduled. It lands in v0.8 alongside the sleep transitions it must
respect and a new explicit item: per-sync Wi-Fi teardown (the git_sync
modem-ownership refactor), prerequisite for both sleep modes. Forward
pointers in typoena-toml.md and the v0.5 spec updated to match; the
v0.5 macroplan learning is left as a historical record.
