fix(chat): recall the current session's prompts by default; tidy the six merged PRs

Input history (#3035) shipped with "All projects" as the default scope and
only recorded prompts sent after the upgrade, so ArrowUp showed other
sessions' prompts and, once switched to "Current session", nothing at all.
Default to the current session and merge the visible transcript's prompts
with the persisted bucket. Existing sessions recall as they did before
#3035, while new prompts keep their attachments and stay recallable after
a revert hides them from the transcript.

Cleanup across #1855, #2297, #3072, #3178, #3035 and #3135: drop the
duplicate poll guards in the file content poller, the zod schema the
VS Code package cannot depend on, a copied file-URL helper and stray
whitespace; move the Enter-to-send strings into the settings namespace;
document OPENCHAMBER_CHATS_DIR, resolve the chats root once on the server
and warm it alongside the other bootstrap calls.

 Chat composer drafts, confirmed mentions, inline-comment drafts, and pinned sessions use the same runtime/directory/session ownership rule. Chat drafts use a bounded shared envelope and notify mounted composers when authoritative deletion clears their identity, preventing unmount autosave from resurrecting deleted text. Inline drafts enforce per-session, global-session, and serialized-byte bounds. Pins retain every valid composite key across runtimes without silent age/count eviction and are never pruned from the first startup list. Confirmed local deletion and routed deletion events clear immediately; after an authoritative baseline exists, a later complete omission also cleans persisted state. Ambiguous session-only legacy drafts and pins are not claimed.
 
-Input history keeps both runtime-wide and runtime/directory/session buckets in one bounded browser-storage envelope. The per-bucket cap is configurable from 1 through 100 and defaults to 40. Lowering the limit trims older entries from every bucket at once and cannot restore what it discards. Every scope change, limit change, append, and session cleanup rereads the latest durable envelope before applying its mutation, so a stale tab preserves history written by another tab. A failed write retains bounded before/after snapshots. The next mutation applies that local delta to the latest durable data, preserving pending appends and session deletions together with unrelated changes from other tabs. A successful durable write clears the pending delta.
+Input history keeps both runtime-wide and runtime/directory/session buckets in one bounded browser-storage envelope. The per-bucket cap is configurable from 1 through 100 and defaults to 40. Recall defaults to the current session's bucket merged with the visible transcript's user prompts; the runtime-wide bucket is opt-in through the Chat setting.

 Server-owned queue acceptance records the original prompt and restorable attachments against its captured runtime/directory/session identity. Rejection records nothing. Automatic delivery and manual take do not record the accepted item again. VS Code retains recording at dispatch, using the full messages actually taken for sending.

 7. Pagination demand must carry the selected session's effective directory. It must not fall back to the sync provider directory because the visible session may belong to another worktree.
 8. The ref-stable loader is disposed only after the current task when its provider unmounts. This lets React Strict Mode's development setup → cleanup → setup probe retain a usable loader for child effects, while real disposal still invalidates the preceding lifecycle's work.
 9. Transcript arrays are chronological by `message.time.created`, with message ID used only as a deterministic equal-time tie-breaker. Message IDs are identity and reconciliation keys, not chronology: OpenCode's fixed-width sortable timestamp prefix rolls over, so a newer `msg_000...` can follow an older `msg_fff...`. Fetch, pagination, materialization, optimistic insertion, events, reconnect inspection, rendering, and revert/undo/redo must preserve this contract.
-10. Transcript visibility and revert markers do not own prompt recall. The sync layer may hide reverted user messages from the visible transcript, but ArrowUp and ArrowDown recall come from the persisted input-history store, scoped by runtime and by runtime + normalized directory + session identity.
+10. Session-scoped ArrowUp and ArrowDown recall merges the visible transcript's user prompts (`useUserMessageHistory`) with the persisted input-history bucket for runtime + normalized directory + session identity. Revert markers hide prompts from the transcript source only; the persisted bucket still recalls them. Global scope reads the persisted runtime bucket alone.
 11. Part arrays preserve authoritative response/event order. Part IDs are identity keys and have the same rollover limitation; identity lookup/removal must not require a part array to be lexically ID-sorted.
 
 Initial loads use smaller pages on constrained VS Code/mobile surfaces. Prefetch resolves only the initial renderable page; it does not eagerly download older history. The mounted chat timeline requests older pages when its viewport is underfilled or the user scrolls toward history, while mobile uses its explicit load-older action. Timeline caches, pending work, prepend snapshots, and stale checks use runtime + directory + session identity so equal session IDs in different worktrees cannot share lifecycle state. Older pages are fetched through the same loader and merged with optimistic records before publication. The same chronology contract applies in the VS Code webview because it consumes this shared loader and sync store; the extension bridge must transport OpenCode records without introducing its own ID-based ordering.
