Adds `telegram.dmIsolation: "shared" | "perUser"` setting. Defaults to "shared" to match Discord DM behaviour (all DMs share the global session). Set to "perUser" to give each DM sender their own isolated session. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Routes each supergroup topic (chat+thread) and optionally each DM user
to its own session key ("tg:<chatId>:<threadId>"), so /reset, /compact,
/status, and /context all operate on the correct isolated session instead
of the global one.

Summary
getTelegramSessionKey()helper that maps each Telegram context to an isolated session key:tg:<chatId>:<threadId>for supergroup topics,tg:<chatId>for general group chat,tg:dm:<userId>for per-user DMs (opt-in), orundefinedto fall through to the global sessiontelegram.dmIsolation: "shared" | "perUser"config setting (default"shared"to match existing Discord DM behavior)/reset,/compact,/status, and/contextto the per-topic session when a key is presentMotivation
Without this, all Telegram group topics share a single global session. A conversation in one topic bleeds context into unrelated topics, and
/resetnukes every topic at once. This matches the isolation pattern Discord already uses for guild channels.Test plan
