refactor: remove #done tag convention and simplify task archival

[x] is sufficient — #done timestamps were redundant ceremony
that agents added inconsistently and git blame already provides.

compact --archive now archives all completed tasks regardless
of age instead of filtering by archive_after_days. Removes
OlderThan, DoneTime, parseDoneTimestamp, TaskDoneTimestamp
regex, and all #done references from docs, skills, templates,
and examples.
