Raise the Telegram polling watchdog default from 90s to 120s and add bounded channels.telegram.pollingStallThresholdMs overrides, including per-account config.\n\nThanks @Vitalcheffe.
* fix(telegram): release undici dispatchers via TelegramTransport.close()
TelegramTransport now exposes an explicit close() that destroys every
owned undici dispatcher (default Agent plus lazily-created IPv4 and
IP-pinned fallback Agents) and the TCP sockets they hold. Dispatcher
constructors are also given bounded keep-alive defaults
(keepAliveTimeout, keepAliveMaxTimeout, connections, pipelining) as a
defence-in-depth layer so the pool cannot grow unbounded even if a
caller forgets to call close().
Without this, every transport that went through a fallback retry left
its fallback Agents anchored forever in a closure; long-running polling
sessions accumulated hundreds of ESTABLISHED keep-alive sockets to
api.telegram.org, saturating the per-IP quota on upstream forward
proxies and making the currently-active outbound node time out while
every other node still tested healthy.
Mock dispatchers in fetch.test.ts gain destroy() spies so the close()
chain is assertable. Call sites that built caller-owned transports from
globalThis.fetch (delivery.resolve-media, test helpers) return an async
no-op close(), matching the new required surface.

* fix(telegram): dispose polling transport on shutdown and dirty rebuild
Every recoverable network error and stall-watchdog trip sets
TelegramPollingTransportState.#transportDirty so the next polling
cycle rebuilds the transport inside acquireForNextCycle(). Previously
the rebuild simply overwrote the field, leaving the old transport's
keep-alive sockets anchored in the now-unreferenced dispatcher — the
polling loop has no natural GC point for these resources, and Node's
object GC never touches OS-level sockets.
acquireForNextCycle() now closes the previous transport (fire-and-
forget so the polling cycle is not blocked by a slow destroy) before
swapping in the rebuilt one. dispose() is a new method that the owning
TelegramPollingSession calls from the finally block of runUntilAbort(),
so a single transport is always tied to a single polling session
lifetime. After dispose(), acquireForNextCycle() returns undefined to
prevent zombie rebuilds.
Under high sustained polling traffic over long-lived sessions, this is
what stops the per-gateway connection count to api.telegram.org from
growing indefinitely and saturating upstream proxy quotas.

* docs(changelog): note Telegram undici dispatcher lifecycle fix

* fix(telegram): disable HTTP/2 for all Telegram polling dispatchers
Undici 8 enables HTTP/2 ALPN by default, but Telegram's long-polling
connections stall on Windows due to IPv6 + H2 multiplexing issues. The
core fetch-guard already sets allowH2:false for guarded paths, but the
Telegram extension creates its own Agent/ProxyAgent/EnvHttpProxyAgent
instances directly from undici without this flag.
Apply allowH2:false to all dispatcher constructors in the Telegram
transport layer, matching the approach used in src/infra/net/undici-runtime.ts.
Fixes#66885
* fix: avoid false telegram polling stall restarts
* fix(telegram): publish polling health liveness
