fix: re-derive conversation authorship from history

Rooms that Reddit returns without timeline events in /sync fell back to
isFromUs=false, so an unanswered opener of ours was projected as inbound
and surfaced in the dashboard's "Needs reply" queue. loadDetails already
paginates the authoritative history for lastMessageSnippet/Time, so take
isFromUs from the same newest message.

 `ChatService` communicates with Reddit's Matrix homeserver, maintains an account-scoped SQLite-backed cache, resolves `t2_` identities to Reddit usernames, and emits sync progress/new-reply callbacks. Startup chooses full or delta sync from persisted cursor state. Operators can explicitly run tracked sync jobs through the versioned API.
 
-`MediaService` resolves Matrix media, downloads it into the persistent data directory, and writes an account-scoped media index. `MediaSyncService` schedules incremental work only while the account is authenticated. The media listing reads persisted indexes for every stored account, including accounts whose runtimes are stopped or require login, and exposes received items only: records attributed to the owning Reddit/Matrix account are excluded, including historical self-sender forms. Private media is served behind the same authorization boundary as the dashboard and APIs.
+Each authenticated account runtime also checks the Reddit profiles represented in its cached conversations every four hours. Profile results are shared process-wide by case-insensitive username, so a recently checked recipient is not looked up again by another account runtime. A valid profile is recorded as active, Reddit's explicit suspension marker is recorded separately, and only an HTTP 404 is recorded as deleted; authentication, rate-limit, network, server, and malformed-response failures do not change the previous state. The dashboard removes deleted recipients from actionable conversation queues and exposes them through the dedicated **Account deleted** bucket.
+
+`MediaService` resolves Matrix media, downloads it into the persistent data directory, and writes an account-scoped media index. Each Matrix message occurrence gets its own gallery record, while repeated occurrences of the same remote asset reuse one private file. Generic download content types are verified from the image bytes before an item is rejected as unsupported.
+
+`MediaSyncService` schedules incremental work only while the account is authenticated. Incremental sync consumes the rooms changed since the durable Matrix cursor; the reported count is the number of rooms Matrix actually returned, not an assumed inbox limit. The cursor advances only after media attachment and cache persistence succeed, so a transient media failure is retried. When Matrix marks a room timeline as limited, chat sync paginates that room's history before advancing the cursor to close the omitted-event gap.
+
+Full media sync walks every joined room and paginates until Matrix reports the end of history. Per-room history or media failures leave the full-sync marker unset and make an operator-triggered full media sync fail visibly; a later full sync can retry the incomplete rooms. Startup may retain the successfully loaded partial cache for availability, but it does not claim that a full backfill completed.

+The snapshot matters: changing configuration later must not silently rewrite the rules for an active conversation. Automation stops for seller/upsell evidence, an image received, a detected boundary, unsafe content, an exhausted turn budget, a repeated media request, or a manual policy.
+
+Two of those stops are terminal rather than handoffs. A reply that pushes the conversation onto another messaging app, asks for contact details, solicits payment, points at a paid-content funnel, or runs the age/bot "verification" scam sets the automation status to `killed`, marks the durable seller flag, and resolves the operator's triage state, so the conversation leaves every actionable queue instead of collecting in the manual one. Detection normalizes the text first — unicode folding, zero-width stripping, leet mapping, separator removal — because these words are routinely obfuscated (`0nlyfans`, `t3l3gram`, `t e l e g r a m`). Ambiguous terms need context: `snap` on its own is a photo request in this product and never a kill on its own. Off-platform kills are a safety control and stay on independently of `reddit.filterSellers`; a configured seller keyword or domain also kills unless `conversations.killOnSellerKeyword` is disabled. Under-18 disclosures and in-person/contact-detail asks remain human handoffs, and now apply to every policy mode rather than the R4R ones only.
+
+Optional second-stage AI screening (`conversations.aiReplyScreening`) runs only when the deterministic rules come up clean, classifies the inbound side of the conversation as genuine, seller, off-platform, scam, bot, or unclear, and kills at or above `killConfidence` while handing off at or above `flagConfidence`. It fails open: a classifier error or outage never blocks a reply, and each inbound event is screened at most once per process. Short refusals are interpreted in sequence: phrases such as “I’m good” become media boundaries only when they answer a media request.
