ci(build-tauri): expose Linux AppImage/deb/rpm bundles as artifacts

[TimeToBuildBob]

Problem

aw-tauri's Tauri bundler already produces .AppImage, .deb, and .rpm files under dist/activitywatch/aw-tauri/ on Linux runs, but the upload-artifact step in .github/workflows/build-tauri.yml only globs dist/activitywatch-*.*. As a result the Linux Tauri bundles were silently dropped from build artifacts (and from drafted releases), even though Linux ZIPs do get uploaded.

This is what @ErikBjare flagged in #1300:

@TimeToBuildBob that PR is to the aw-tauri repo, not this bundle repo. PR needed to this repo too.

Change

Add a Linux-only Package Linux (Tauri bundles) step that copies the bundler outputs out with versioned, arch-suffixed filenames so they match the existing upload glob:

• activitywatch-tauri-${VERSION_WITH_V}-linux-${ARCH}.AppImage
• activitywatch-tauri-${VERSION_WITH_V}-linux-${ARCH}.deb
• activitywatch-tauri-${VERSION_WITH_V}-linux-${ARCH}.rpm

shopt -s nullglob keeps the step a no-op if any extension is missing (e.g. if rpm packaging is disabled in tauri.conf.json for some build), instead of failing on a literal *.rpm glob.

Out of scope

• No changes to Windows or macOS jobs
• No changes to build.yml (non-Tauri build, already has its own AppImage/deb steps)
• aw-tauri's own arm64 ARCH detection is broken (uname -m returns aarch64 on Linux arm64 but the Makefile checks for arm64); that's an aw-tauri Makefile bug, not part of this PR

Verification

• YAML parses (python3 -c "import yaml; yaml.safe_load(open('.github/workflows/build-tauri.yml'))")
• Workflow lint will run on the PR
• Final verification will be the next master push, where the Tauri Linux runs should produce activitywatch-tauri-*-linux-x86_64.{AppImage,deb,rpm} artifacts visible in the workflow run

Closes the bundle-repo half of #1300.

Greptile Summary

This PR fixes a gap in the Tauri build pipeline where Linux .AppImage, .deb, and .rpm bundles produced by the Tauri bundler were silently excluded from uploaded artifacts because the upload glob (dist/activitywatch-*.*) only matched files directly in dist/, not those nested under dist/activitywatch/aw-tauri/.

• New Linux packaging step runs after make package, reads VERSION_WITH_V from the environment and uname -m for architecture, then copies each bundle type into a flat dist/activitywatch-tauri-${VERSION_WITH_V}-linux-${ARCH}.${ext} path that the existing upload step already picks up.
• Robustness guards: shopt -s nullglob makes the step a no-op for absent bundle types; an explicit count check (0 → skip, 1 → copy, >1 → exit 1) prevents silent overwrites and fails fast on unexpected duplicates.

Confidence Score: 5/5

Safe to merge. The change is additive and Linux-only, with no impact on macOS or Windows jobs.

The new step is guarded by runner.os == 'Linux', uses only well-established bash constructs (nullglob, array count via ${#files[@]}, case), and relies on VERSION_WITH_V already written to $GITHUB_ENV by an earlier step. The resulting filenames match the existing dist/activitywatch-*.* upload glob. The previous review concern about silent overwrites has been addressed with an explicit count check that exits non-zero on unexpected duplicates.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/build-tauri.yml	Adds a Linux-only packaging step that copies Tauri bundles (.AppImage/.deb/.rpm) into versioned, arch-suffixed filenames matching the existing upload glob; uses nullglob + count guard to handle missing or unexpected duplicate files safely.

So the bundle-repo half of #1300 is working as intended on both Linux architectures. I tried to merge / enable auto-merge from here, but this token does not have the required repo permissions.
