Production polish: i18n shelved, PWA icons, SEO/GEO cleanup, UX fixes

Big-picture changes since 01be8e7:

New routes — /trump /btc /kol /trades /analytics /archive plus four
SEO landing pages (/methodology /glossary /case-studies /contact),
all served under /[locale]. Each has dedicated metadata + JSON-LD.

KOL page (new) — DigestWidget + OnchainWidget + TalkVsTradesWidget,
filter by handle/ticker, click-through to per-post detail with the
original AI-extracted ticker/conviction/quote.

BTC page (new) — tabbed: macro-bottom (AHR999 + 200WMA + Pi Cycle)
and funding-rate reversal, with live sparkline + threshold bands.

Telegram card on Settings — wallet-link code generation, status,
disconnect. Preferences moved into the bot itself (/trump /btc etc.)
so the card stays minimal.

SignalMonitor (new) — ETH/LINK Bollinger breakout monitor in its own
component, shares the singleton WsProvider so no second WS opens.

WS singleton refactor (lib/wsContext) — shared WsProvider + useWsSubscribe
hook. Cleanup now actively closes the socket on unmount; previously the
local `ws` couldn't be reached from cleanup and leaked one connection
per StrictMode remount.

OpenPositions polling no longer pops MetaMask in the background —
splits into load('first') for user-initiated and load('poll') that
uses getCachedViewEnvelope without signing.

i18n shelved — proxy.ts (Next 16 middleware rename) wires next-intl
but only Navbar + layout footer have translations. Rest of UI used
isZh ternary scattered across 28 files. All `const isZh = locale === 'zh'`
flipped to `const isZh = false` so every site renders English; Chinese
branches kept as dead code so revival is one regex away.
LanguageSwitch hidden but file kept. zh-CN hreflang removed from
metadata + sitemap to avoid duplicate-content penalties.

Wallet error handling — lib/walletError.ts: isUserRejection walks EIP-1193
code 4001 + .cause chain; previous string-match for "reject"/"denied"
broke for users running MetaMask in non-English UIs. 12 call sites
migrated across 5 components.

PWA icons — app/icon.tsx + app/apple-icon.tsx render the brand "α" via
Next's ImageResponse so no static PNG asset is required. manifest.ts
references /icon and /apple-icon dynamic routes.

OG image + sitemap + robots — dynamic 1200×630 OG card; robots blocks
both /en/settings and /zh/settings; sitemap only emits /en routes;
JSON-LD covers SoftwareApplication + Organization + 10-Q FAQPage.

Landing page polish — Launch Dashboard button stripped of magnetic
hover + shimmer + lift + glow expansion (multiple users found it busy);
hero scramble alphabet swapped to alphanumeric (was block characters);
"15 KOL feeds" copy updated to 19 in 5 places.

PostCards source icons — new entries for btc_bottom_reversal,
funding_reversal, kol_divergence so they no longer fall through to
the generic "first letter" fallback.

Archive page filter — excludes funding_reversal + kol_divergence
(previously only excluded truth + btc_bottom_reversal so new live
signals leaked into the legacy archive).

Cache + skeleton loading — lib/cache.ts SWR module with per-key TTL,
applied across the major pages so navigation feels instant.

SignConfirmSheet — 4 hardcoded Chinese strings translated to English
(English users were seeing zh-only "需要钱包签名" etc).
