test(#297 review): pin table->markdown at the output level (F1)

The existing tests assert only the classifier flags ({asMarkdown, wrapBareRows}),
not the resulting markdown. Add two output-level tests via htmlToMarkdown mirroring
the serializer's real path: (a) a header-less bare-rows selection wrapped as
<table><tbody><tr>… yields a VALID GFM pipe table (GFM plugin synthesizes an empty
header + separator), and (b) a whole table with a header round-trips to a proper
pipe table with header/separator/data rows. Both are non-vacuous — they fail
against the old one-value-per-line serialization (no separator row, no pipes).

+- **Dock the AI chat window into the side menu.** The floating chat window can
+  be pinned to the sidebar — drag it onto the navbar (a drop-zone highlight
+  shows where it lands) or use the new "Dock to sidebar" header button; while
+  docked it fills the sidebar area and follows its live size. "Undock" (or
+  dragging it back out) restores the floating window, a collapsed/absent
+  sidebar falls back to floating, and the docked state survives a reload.
+  (#276, #282)
+- **Hovering commented text shows the comment thread in a tooltip.** Pointing
+  at a highlighted comment mark pops a small card with the author and plain
+  text of the root comment and its replies, so a thread can be skimmed without
+  opening the side panel. The card appears after a short delay (no flicker on a
+  passing glance), skips resolved and text-less threads, and dismisses on
+  scroll or click — clicking a mark still opens the comments panel. (#268,
+  #271)
+- **"Move to trash" button in the temporary-note banner.** Besides "Make
+  permanent", the banner on an open temporary note now also offers to trash the
+  note immediately instead of waiting out its lifetime. It reuses the regular
+  soft-delete path, so the "Page moved to trash" undo toast is the safety net —
+  no confirmation dialog. (#273, #277)
+- **Code-block controls float as an overlay instead of taking a row above the
+  code.** The language selector and copy button now sit in the block's top-right
+  corner, and the selector stays invisible until the block is hovered or the
+  selector is focused, so reading code is chrome-free. In read-only views only
+  the copy button renders. (#275, #278)
+- **The AI agent is told about your page edits between turns.** The server
+  snapshots the open page's Markdown at the end of every agent turn and, on the
+  next turn, injects a unified diff of what changed in between, so the agent
+  knows its earlier copy of the page is stale and builds on the user's edits
+  instead of reverting or overwriting them. The diff is whitespace-normalized
+  (pure formatting churn injects nothing) and size-capped, with a hint to
+  re-read the full page via `getPage` when truncated. (#274, #281)
+- **Stress-accent button (U+0301) in the bubble menu.** Select a vowel and
+  toggle a combining acute accent over it — a Russian-style stress mark. The
+  accent is stored as plain text (no custom mark), so it survives Markdown/HTML
+  export, full-text search and public shares unchanged; the toggle is a single
+  undo step and re-clicking removes the accent. (#270, #280)
+- **Reading position survives a reload.** The editor remembers how far you
+  scrolled in each page (per tab, in `sessionStorage`) and restores that
+  position after an F5 or reopening the document, waiting for the collaborative
+  content to finish laying out first. A URL `#hash` anchor still wins — restore
+  is a no-op then. (#266, #267)
+- **The slash menu finds commands typed in the wrong keyboard layout.** A query
+  typed with the wrong layout active (e.g. `/сщву` for `/code`, or `/cyjcrf`
+  for the Cyrillic «сноска» → Footnote) is additionally remapped ЙЦУКЕН↔QWERTY
+  by physical key position and matched against the commands; genuine Cyrillic
+  search terms keep priority over remapped candidates, and short wrong-layout
+  prefixes match by command title. (#283, #285, #287)
