docs: write real v1.0.4 changelog and auto-generate release notes in release script

- CHANGELOG.md: replace v1.0.4 placeholder section with the actual changes
  (Lightning Wallet Connections/NWC, Hub version badges, backup overhaul,
  automated releases, security hardening, fixes)
- release-stable.sh: generate categorized Keep-a-Changelog release notes
  from commits since the last tag (feat/fix/docs/security grouping),
  let the user review/edit before publishing, and use the same notes for
  CHANGELOG.md, the GitHub release, and the Gitea release
- Fix broken /api/ path in the v1.0.4 changelog release link
- Build Gitea API payload with jq/python so multi-line notes are JSON-safe

 ## [1.0.4] - 2026-07-29
 
 ### Added
-- (Add new features here)
+- **Lightning Wallet Connections (NWC)** — Hub-managed Nostr Wallet Connect powered by Alby Hub + LND:
+  - Create, view, and delete wallet connections directly from the Sovran Hub with a tabbed modal UI
+  - Downloadable/printable LNURL QR codes for connecting external wallets
+  - Channel liquidity guide and onboarding guidance for new LND nodes
+  - Unique-hostname enforcement with conflict validation and UI guidance
+  - Official NWC branding and logo
+- **Version visibility across the Hub**:
+  - Sovran_SystemsOS version badge displayed under the Hub title
+  - Version numbers shown on all Hub service tiles and next to service modal titles
+  - Deployed PHP app versions surfaced in service titles
+  - Build-time version reference file (`VERSION`) so version lookups are instantaneous and consistent
+- **Automated stable release workflow** (`scripts/release-stable.sh`) with versioned ISO naming from the `VERSION` file
+- `CONTRIBUTING.md` and expanded project documentation
 
 ### Changed
-- (Add changes here)
+- **Manual Backup overhauled**: replaced tar+DB+LND archive approach with a reliable ext4 + rsync workflow, including
+  mount checks, path safety, atomic completion markers, stale-marker cleanup, and behavioral test coverage
+- **Port-forwarding UX simplified**: removed onboarding Step 4 and the misleading local "ready" status;
+  Njal.la DDNS now runs automatically when the feature is enabled
+- README restructured for clarity, links, and accuracy; added router/ISP port-forwarding requirements
+  for Server + Desktop mode; acknowledged LiveKit and Alby Hub
+- Updated nixpkgs and Bitcoin clients
+- Repository cleanup: removed unused `.github`, `.tests`, `nix/`, and `docs/ai` directories
 
 ### Fixed
-- (Add bug fixes here)
+- NWC wallet certificate path wiring (now uses the nix-bitcoin LND cert path)
+- Deterministic LND/Alby Hub port collision
+- Alby Hub executable resolution and v1.23.0 patches regenerated against exact upstream source
+- Manual Backup exit-code failures (bash/gawk in service PATH, tar tolerance, flock, browser-cache exclusions)
+- rsync destination-directory failures in backups (auto `mkdir -p`, mount check, 19 behavioral tests)
+- `sovran-hosts-update` converted to `writeShellApplication` with explicit runtime inputs
+- Incorrect `lib.mkIf` usage in the NWC wallets module
+- Duplicate systemd LND strings
+- `git fetch` tag-clobber errors against Gitea (now uses `--force`)
 
-[1.0.4]: https://git.sovransystems.com/api/Sovran_Systems/Sovran_SystemsOS/releases/tag/v1.0.4
+### Security
+- Hardened Lightning Wallet Connections (NWC): restricted `ReadOnlyPaths` for the unlock password,
+  fixed an Authorization-header bug, eliminated stack-trace exposure flagged by CodeQL,
+  and tightened credential access and amount validation
+
+[1.0.4]: https://git.sovransystems.com/Sovran_Systems/Sovran_SystemsOS/releases/tag/v1.0.4
