feat: resource caps, Saved Messages, author walls, docs for node bring-up
Node flags (cmd/node/main.go):
--max-cpu / --max-ram-mb — Go runtime caps (GOMAXPROCS / GOMEMLIMIT)
--feed-disk-limit-mb — hard 507 refusal for new post bodies over quota
--chain-disk-limit-mb — advisory watcher (can't reject blocks without
breaking consensus; logs WARN every minute)
Client — Saved Messages (self-chat):
- Auto-created on sign-in, pinned top of chat list, blue bookmark avatar
- Send short-circuits the relay (no encrypt, no fee, no mailbox hop)
- Empty state rendered outside inverted FlatList — fixes the mirrored
"say hi…" on Android RTL-aware layout builds
- PostCard shows "You" for own posts instead of the self-contact alias
Client — user walls:
- New route /(app)/feed/author/[pub] with infinite-scroll via
`created_at` cursor and pull-to-refresh
- Profile screen gains "View posts" button (universal) next to
"Open chat" (contact-only)
Feed pipeline:
- Bump client JPEG quality 0.5 → 0.75 to match server scrubber (Q=75),
so a 60 KiB compose doesn't balloon past 256 KiB after server re-encode
- ErrPostTooLarge now wraps with the actual size vs cap, errors.Is
preserved in the HTTP layer
- FeedMailbox quota + DiskUsage surface — supports new CLI flag
README:
- Step-by-step "first node / joiner" section on the landing page,
full flag tables incl. the new resource-cap group, minimal
checklists for open/private/low-end deployments
