docs: document the 55 features missing from LOTUS_FEATURES.md; refresh the Synapse re-check (#294)

LOTUS_FEATURES.md had not been updated since September and was missing
55 shipped features. Add a "June–October 2026 Additions" section,
grouped by area, one line per feature with its commit and issue.
LOTUS_REFERENCE.md's blocked-features note is re-checked against
production Synapse 1.162.0.

Fixes #294

+## June–October 2026 Additions
+
+Features shipped since the sections above were last updated (Gitea #294). Each
+line names the commit that introduced it.
+
+### Calls
+
+- **Selectable ringtone + volume:** pick the incoming-call ringtone (`4a875884`).
+- **In-call incoming-call banner:** a small banner for a second call instead of a full ring (`c67aed01`).
+- **Denoise tester:** Settings → Calls lets you audition the ML models and calibrate the noise gate (`14cfa021`).
+- **Mic level meter** on the mute button (`3449338b`, #146).
+- **"You're muted" nudge** when you talk into a muted mic (`73b1d1e3`, #117).
+- **Undeafen catch-up toast:** what you missed while deafened (`33e16e85`, #128).
+- **Admin turned off screen share / camera:** a toast explains why your share or camera stopped (`34574178`, #223).
+- **Voice-limit / audio-only chip** in the room header (`7f17940d`, #134).
+- **"N Live" pill names** who is in the call on hover / focus (`a475531b`, #157).
+- **Live-call dot on the space rail** (`4fe9c870`, #148).
+- **Missed-call line** in the timeline for DMs and small groups (`c921f115`, #162).
+- **Answer with camera or audio-only:** answering says when it turns the camera on (`d2f56817`, #135).
+- **Audio output quick-switch** in the call bar (`98c80f36`, #119).
+- **Call-ended summary toast:** "Call ended · 41 min · connection was good" (`af1c0ee1`, #143).
+- **No WebRTC on desktop:** offers "Open in browser" instead of a dead end (`fff583fc`).
+- **Call page on its own origin** (desktop, opt-in) (`7d7a379c`, #43).
+
+### Messaging & composer
+
+- **Reactions collapse** to one row with a +N chip (`bf05751e`, #138).
+- **Consecutive photos / videos** render as one gallery grid (`bd8c79e0`, #137).
+- **Inline audio playback** for `m.file` audio attachments (`eb34b047`).
+- **Recently used GIFs** in the GIF picker (`5b58e5fe`).
+- **Pasted image → caption field:** a single pasted or dropped image lands in its caption (`0c45bde8`, #129).
+- **Offer to format pasted code** as a code block (`75d55e86`, #107).
+- **Tap to preview stickers / GIFs** on touch, tap again to send (`8d11a62e`, #147).
+- **Link-mismatch confirmation** before opening a link whose text names another site (`74d8e311`, #122).
+- **Embed fallback** for hung embeds and deleted X posts (`ba5b1ffe`, #200).
+- **"Back to where you were"** after jumping in the timeline (`7da91bd8`, #127).
+- **Offline outbox:** unsent messages survive a reload and retry (`02d86cae`, #112).
+- **Terms-consent explanation** when "Failed to send" is the server wanting its terms accepted (`c96c47dd`).
+
+### Search & navigation
+
+- **Quick switcher (Ctrl/⌘+K)**, with a configurable key (`9d4679d2`).
+- **Search filters:** `has:image/file/video`, recent searches, pinned only (`1ee0f0b5`).
+- **Search operators:** `in:`, `before:` / `after:`, `has:`, `is:pinned` (`75951f90`, #106).
+- **Explore:** featured Lotus Guild space and the matrixrooms.info directory (`b1ecb0c4`).
+
+### Rooms & threads
+
+- **Disappearing messages** (MSC1763 `m.room.retention`) (`82e52e1b`).

 ## 🚫 Blocked Features (server / upstream gated)
 
-Re-run `/_matrix/client/versions` + `unstable_features` after each Synapse upgrade. **Re-checked on 1.157.1 (2026-07-23): no change — all four below are still `false`.** The 1.156.0→1.157.1 delta unblocked nothing (it's a bugfix release; the only feature-bearing release in the gap was 1.156.0, which we were already running).
+Re-run `/_matrix/client/versions` + `unstable_features` after each Synapse upgrade. **Re-checked on 1.162.0 (2026-10-18, Gitea #294):** live location (`msc3489`/`msc3672`) and relation redaction (`msc3892`) are still unadvertised; thread subscriptions (`msc4306`), sticky events (`msc4354`) and QR login (`msc4108`) are still `false`. New: `org.matrix.msc3026.busy_presence` is advertised as `false`, and enabling it would give Do Not Disturb a real presence state (#283). `msc3266` and `msc4222` are no longer listed, but room preview still works (`im.nheko.summary` and `v1/room_summary` both answer 200). (Previous check: 1.157.1 on 2026-07-23, no change then.)
 
 - **[BLOCKED] Live Location Sharing** (MSC3489 + MSC3672 both `false`) — real-time GPS beacons over the existing static share.
 - **[BLOCKED] Reaction/Relation Redaction** (MSC3892 `false`) — remove a reaction without redacting the parent; current full-redaction fallback is acceptable.
