morluto df8b4d8a5a fix(process): token-check identityless exit-refresh replacements (#5675 )

* fix(process): token-check identityless exit-refresh replacements

A launcher-exit refresh could drop a reparented grandchild that was absent
from the prior snapshot and report cleanup complete, or publish a verified
empty lineage, without reading its run token.

Fixes #5206

* fix(process): re-read identityless refresh rows when relations change

Lineage refresh classified every pre-existing process as a newcomer, and it
skipped a row after caching its first parent and group. Seed the exclusion
set from the initial snapshot and read a row again when that relation changes.

* style: format files oxfmt rejects on main

Repo-wide format:check fails on these two files at current main. Align them
so the process-ownership fix can pass the required static check.

* fix(process): keep owned groups found while confirming exit

An unreadable exit-refresh row used to hide the confirmation table, and
revalidation dropped groups discovered after the plan was built. Both now
stay in the same cleanup, and confirmation reads are bounded.

* fix(process): reclassify lineage rows when tree membership changes

Initial outsiders and cached refresh rows are read again when a parent,
group, or ancestor move changes launcher-tree membership. Unchanged
initial rows stay unread.

* fix(process): re-read cached identityless lineage tokens

Parent and group do not identify a process generation. A row whose token
was read is read again on the next refresh, so a reused PID cannot keep
a verified descendant.

* fix(process): revalidate an owned group that reappears

A group discovered after it was already processed is queued once more.
Another appearance stays unresolved instead of reporting cleanup complete.

* fix(process): recheck a helper that changes groups during confirmation

The confirmation table can move a token-matched member into a new group.
That row is read again, and cleanup signals the group it belongs to now.

* fix(process): publish one lineage row when a descendant returns

A refreshed descendant replaces the initial row for the same PID, including
when its group moves away and then returns to the original relation.

* fix(process): re-read foreign PIDs on the exit confirmation table

A readable foreign token does not identify a process that later reuses
that PID. The confirmation table reads those newcomers again.

* fix(process): recheck a pre-exit PID whose relation changes

An unchanged pre-existing row stays unread. A prior PID whose parent or
group changed is token-checked, so a reused owned process is not skipped.

* fix(process): recheck an initial descendant after its token matches

A successful read in the first lineage pass marks that PID token-checked.
A later refresh reads it again, so a reused PID cannot stay verified.

* fix(process): recheck the launcher on each lineage refresh

A later refresh reads the launcher PID again. A missing or unowned
launcher is unavailable instead of rooting a verified lineage.

* fix(process): publish lineage from the latest refresh table

A descendant missing from the latest refresh is omitted. A refreshed
launcher whose group or command no longer matches stays unavailable.

* test(process): cover a refreshed launcher parent mismatch

A same-token launcher whose parent no longer matches the committed
expected parent is unavailable, same as a group or command change.

* fix(process): recheck a token-read helper that returns to its group

A confirmation table dropped a previously matched PID once its parent and
group matched the pre-exit row, so cleanup could signal only the group it
had joined and report success while that helper survived.
