docs(specs): adopt status-heading lifecycle convention across specs

Migrate 29 legacy specs off the old shape (a status suffix in the filename plus a :STATUS: property drawer) onto the docs-lifecycle status heading: a top-level heading carrying the org lifecycle keyword and a dated history line, with the two #+TODO sequences in the header.

Dropping the -doing/-implemented/-superseded suffixes means a status change no longer forces a rename and link surgery. Each keyword comes from the spec's own recorded status. The four specs already on the heading form are untouched, and every inbound reference now points at the new names.

The status board is one grep: rg '^\* (DRAFT|READY|DOING|IMPLEMENTED|SUPERSEDED|CANCELLED) ' docs/specs/
