chore(release): v1.9.26 — batch Apps Script edge-DNS cache

Ship PR #958 by @dazzling-no-more.

CodeFull.gs now resolves DNS candidates in two passes, using one CacheService.getAll(keys) lookup per tunnel batch and reusing successful DoH answers inside the same batch. Long qnames now get SHA-256 cache keys instead of skipping cache, while parse/DoH failures still fall back to the tunnel-node path.

+• **بهینه‌سازی Full mode Apps Script: batch کردن Edge-DNS cache lookupها** ([PR #958](https://github.com/therealaleph/MasterHttpRelayVPN-RUST/pull/958) by @dazzling-no-more). مسیر `CodeFull.gs` قبلاً برای هر DNS query داخل batch یک `CacheService.get` جداگانه می‌زد. روی batchهای شلوغ، همین چند round-trip داخلی به CacheService می‌تونست latency بسازه، مخصوصاً وقتی چند lookup مشابه پشت سر هم می‌اومدن. حالا DNS candidateها در دو pass پردازش می‌شن: اول همه keyها جمع می‌شن، بعد یک `cache.getAll(keys)` برای کل batch انجام می‌شه، و جواب‌های DoH موفق هم داخل همان batch دوباره استفاده می‌شن تا query تکراری دوباره به resolver نخوره.
+
+• **مسیر امن fallback حفظ شده**. اگر CacheService خطا بده، DoH هنوز از داخل شبکه Google انجام می‌شه ولی `cache.put` غیرفعال می‌مونه؛ اگر parse/DoH شکست بخوره، همان op مثل قبل به tunnel-node forward می‌شه. qnameهای خیلی بلند هم به‌جای skip شدن، با SHA-256 زیر namespace جداگانه cache می‌شن تا محدودیت ۲۵۰ کاراکتری key در CacheService شکسته نشه. هیچ config migration یا تغییر سمت client لازم نیست؛ فقط `CodeFull.gs` جدید را deploy کنید.

+• **Optimize Full mode Apps Script by batching Edge-DNS cache lookups** ([PR #958](https://github.com/therealaleph/MasterHttpRelayVPN-RUST/pull/958) by @dazzling-no-more). `CodeFull.gs` previously issued one `CacheService.get` per DNS query inside a tunnel batch. On busy batches, those repeated internal CacheService round-trips could add avoidable latency, especially when several lookups repeated the same qname/qtype. DNS candidates now run in two passes: collect all cache keys first, perform one `cache.getAll(keys)` for the whole batch, then reuse successful DoH answers inside the same batch so duplicate queries do not hit the resolver again.
+
+• **The safe fallback behavior is preserved**. If CacheService fails, DoH still runs from inside Google's network but `cache.put` is skipped; if parse/DoH fails, the op falls back to the existing tunnel-node forward path. Very long qnames now use a SHA-256 cache key under a separate namespace instead of skipping cache entirely, keeping keys below CacheService's 250-character limit. No client config migration is required; deploy the new `CodeFull.gs`.
