Tp-Note: matoleo yote na matoleo ya zamani

Tp-Note v1.26.5
A maintenance and infrastructure release that unifies the build and release
process on GitHub Actions, producing a single flat set of standard-named assets.
- New complete-build CI: one flat, standard-named asset set
(tpnote--.{tar.gz,zip}, .deb, .msi, plus docs and winget
archives), built once and published to the GitHub release.
- GitHub is now the single release publisher: removed the Azure Release stage
that duplicated assets under a different naming scheme.
- Winget InstallerUrl now points to the GitHub release MSI.
- Hardened build scripts (robust artifact copy, docs cleanup) and streamed live
nix build logs.
- Refactored the distribution docs to point at the GitHub releases page (with an
asset table) and consolidated the documentation build.
Installers and standalone binaries for Windows, macOS, Linux and Debian/Ubuntu
are attached below.
