feat(web): refresh marketing site — accurate timeline, live changelog, cross-boundary positioning

The site had drifted ~6 months behind the product. Three problems
addressed in one push:

1. Timeline ("Shipped, not promised") topped out at v0.6–0.8 and
   claimed "66 npm releases" — both stale. Adds a v0.9 → 1.34 tier
   covering daemon, multi-mesh, multi-session correctness train,
   refuse-to-kick on control-plane, env-var fallback. Updates count
   to "120+ npm releases through v1.34.15." Rewrites the "next"
   block from the now-shipped "Daemon redesign · per-topic
   encryption" to the actually-pending "HKDF cross-machine identity
   · session capabilities · A2A interop · self-host packaging ·
   federation."

2. Hero subhead leaned into the original "Claude Code peer mesh"
   framing, which is undercut by Anthropic Agent Teams (Feb 2026,
   single-machine native mailbox). Now reframes claudemesh as the
   encrypted backbone where Claude Code sessions, autonomous
   agents, and humans coordinate "across machines, across users,
   across organizations" — the four words that distinguish the
   product from anything Anthropic structurally can ship from
   inside Claude Code.

3. /changelog had three entries from April 2026 (v0.1.2 → v0.1.4)
   and was 70+ versions out of date. Replaced with a curated
   16-entry timeline from v0.1.0 → v1.34.15, hand-picked to tell
   the story (load-bearing ships, not every patch). Adds links
   back to docs/roadmap.md, .artifacts/specs/, and GitHub Releases.

New module: apps/web/src/modules/marketing/home/changelog-data.ts
holds the curated entries as a single source of truth. Imported by
both the /changelog page and a new home-page component
LatestReleases (compact 5-entry strip, slotted between Timeline
and Pricing) so they never disagree.

Misc fixes pulled in:
- timeline.tsx had glyph="layers" which isn't in SectionIcon's
  valid set; switched to "grid" (changelog-data.ts uses same).
- changelog data extracted to a non-route module so Next.js's
  route-export validator stops complaining about exporting
  CHANGELOG_ENTRIES from app/.../changelog/page.tsx.

Pre-existing typecheck noise in packages/ui/web/sidebar.tsx
(csstype version mismatch) + billing modules unrelated to this
change. My files all typecheck clean.
