docs(adr): use standard decision-axis status vocabulary

dfa1 · claude · dfa1 · commit 424a4355d85d · 2026-06-27T08:53:26.000+02:00
Drop the non-standard "Completed" ADR status, which conflated two axes: a
decision's state (Proposed/Accepted/Deprecated/Superseded) versus whether the
work shipped. Map every "Completed" to "Accepted"; the existing Released column
already carries the shipped-ness axis (version, or blank when not yet shipped).
Rewrite the status-values legend accordingly.

No decisions change — only the label. ADR-literate readers track decision-state
and implementation-state separately, so Status now holds only the former.
