Add actions/attest-build-provenance to both build workflows so every
binary is attested in the same job that builds it, the only point
where provenance meaningfully proves an artifact was built from source
rather than uploaded by hand.
release.yml (build-tauri): grant id-token and attestations write
permissions, then attest the desktop bundles via the tauri-action
artifactPaths output, the Android apks, and the Windows portable exe.
nightly.yml (build): same permissions plus one step attesting the
staged nightly-out binaries. Nightlies ship via download.readest.com,
but gh attestation verify is digest based so it verifies them too.
Verify a download with:
gh attestation verify <file> --repo readest/readest
