Promotes the deltas from openspec/changes/add-explore-page/ into
top-level specs after the implementation landed in #321.
- New top-level spec: openspec/specs/explore/spec.md (paginated local
user directory at /explore, with the "Active recently" sub-section,
exclusion rules for private profiles and the demo persona, offset
pagination, and the navbar entry rule).
- Updated openspec/specs/journal-landing/spec.md with the new
"Visitor home links to /explore" requirement.
- Updated openspec/CAPABILITIES.md with an entry under Social.
- Moved openspec/changes/add-explore-page/ to
openspec/changes/archive/2026-04-26-add-explore-page/.

Stream F from docs/information-architecture.md. Closes the gap between
"I want to follow someone on this instance" and "I have a username
from outside the app."
This change is the OpenSpec proposal only — the four artifacts
(proposal.md, design.md, specs/, tasks.md) plus a new top-level spec
target at openspec/specs/explore/. Implementation lands in a follow-up
PR via /opsx:apply.
Key decisions captured in design.md:
- Anonymous access is allowed (the data shown is already public, and
it's a stronger first-visit experience).
- Directory order: MAX(activities.created_at) DESC NULLS LAST,
tiebreaker users.id DESC. Recency-of-activity is the simplest signal
that meaningfully reflects "who's active here right now."
- "Active recently" sub-section: same query, sliced — top 5 users
with a public activity in the last 30 days, hidden when empty.
- Privacy filter: profile_visibility = 'public' AND not the demo
persona AND (forward-compat) not banned/suspended.
- No search in v1 — deferred until the user count makes it actually
useful. /users/<username> already partially solves it.
- Offset pagination (?page=, ?perPage=, capped 100). Cursor
pagination is the right answer at ~10K users; not now.
- Navbar gets an "Explore" entry for signed-in users; anonymous
visitors reach /explore via a link on the visitor home.
