release: v7.6.4 — Windows DR-stream guidance + combined demo SVG

Docs / help-text only. Flags PowerShell's `>` binary corruption pitfall
in the --stream help text and in DISASTER_RECOVERY.md, plus a 7-Zip
extraction note for AES-256 archives. Combines the 7 demo SVGs from
v7.6.2 into one 113-second sequential animation to keep the README
scrollable.

No code path, config, or repository format changes.

+## [7.6.4] - 2026-05-25
+
+### 📚 Windows DR-stream guidance + single combined demo SVG
+
+**Why:** A real user hit a confusing failure path on Windows:
+`ssh ... disaster-recovery export --stream > recovery.zip` from
+PowerShell produced a 14 KB file (twice the real size) that 7-Zip
+rejected as "not an archive". Root cause is PowerShell 5.1's `>`
+operator re-encoding stdout as UTF-16 LE — which corrupts the
+binary stream. The same code path works fine from cmd.exe, scp, or
+any Linux/macOS client. Separately, the seven demo SVGs added in
+v7.6.2 stacked vertically and made the README scroll-heavy.
+
+**Changes:**
+- `--stream` `--help` text now flags the PowerShell pitfall right at
+  command-line discovery time and points at the DR docs.
+- `README.md` gains an inline Windows note next to the SSH-stream
+  example and a stronger 7-Zip hint at the extraction step.
+- `docs/DISASTER_RECOVERY.md` gets two new subsections under "SSH
+  Stream Mode": **Windows clients** (scp-from-server-side-file pattern,
+  cmd.exe `>` pattern, post-transfer byte-magic verification) and
+  **Extracting on Windows** (Explorer's lack of AES-256 ZIP support,
+  recommended tools: 7-Zip / NanaZip / WinRAR).
+- README "What it looks like" replaces the 7 individual demo SVGs
+  with a single 113-second sequential animation
+  (`demo-combined.svg`, 743 KB) that plays all scenes back-to-back
+  with banner cards. The 7 individual SVGs are preserved and exposed
+  via a collapsible table for direct access.
+
+**Upgrade notes:** Docs / help-text only. No code path, config, or
+repository format changes — `pip install --upgrade kopi-docka` (or
+`pipx upgrade kopi-docka`) to pick up the new `--help` output.
+Windows users currently fighting PowerShell binary streams should
+switch to one of the patterns in the docs.
