feat(cli): show installer and update download progress

[juliusmarminge]

Release downloads currently go quiet during slow installs and updates. Both installers get a compact T3 mark. Installers and t3 update share muted labels, a blue download bar with received and total MB, and one status line for verification and extraction. Updates keep the output compact without a logo. The finish shows how to start T3 instead of the internal runtime layout.

No new runtime dependencies. The shell installer remains compatible with Bash and POSIX sh at 227 lines. It measures the archive that curl or wget is already writing, preserves download failures, and stops its child on interruption. PowerShell uses the built-in .NET HTTP client for progress and keeps native progress on older consoles without ANSI or glyph support. The CLI redraws at most ten times per second, including a final byte count for downloads without Content-Length. Redirected output remains plain, and NO_COLOR is respected.

Verification: 26 focused tests, targeted lint, server and scripts typechecks, and Bash/dash syntax checks passed. Terminal integration tests cover a gated partial download and an HTTP failure. Manual checks cover wget, redirected output, cached installs, checksum rejection, Ctrl-C cleanup, and a fast download without Content-Length. PowerShell 7.4 completed a full fixture install on Linux, including download integrity, extraction, and launcher creation. A full fixture install also passed with forced ASCII console encoding, using plain stages and native progress. CLI tests and PowerShell PTY checks cover widths down to one column, including known and unknown download sizes. Native Windows/PowerShell 5.1 remains unverified.

These screenshots and recordings replay actual PTY output in xterm.js, using the same 2 MiB local release fixture and terminal dimensions for the base and head. The fixture executable only answers --version; the PowerShell fixture uses a shell executable named t3.exe on Linux.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds substantial terminal-progress behavior to the update flow and both customer-facing installers, including new streaming download and interruption-handling paths. It also introduces a file-level suppression for a static-analysis diagnostic in the new integration test.

🟡 Minor · Fit the known-length download line to the terminal width. · install.ps1:54

scripts/install.ps1:54
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fit the known-length download line to the terminal width.

$interactive checks redirection, TERM, virtual-terminal support, and glyph encoding, but not [Console]::WindowWidth. The known-length branch still emits a 32-cell bar, so it can wrap on a sufficiently narrow supported terminal. Compute the available bar width and use a bounded compact layout when the counters do not fit.

Proposed fix

+  $columns = [Console]::WindowWidth
   if ($total -gt 0) {
     $percent = [Math]::Min(100, [Math]::Floor($bytes * 100.0 / $total))
-    $filled = [int][Math]::Floor($percent * 32 / 100)
+    $details = ("{0,3}%  {1:F1} / {2:F1} MB" -f $percent, ($bytes / 1MB), ($total / 1MB))
+    $width = [Math]::Min(32, $columns - 4 - $details.Length)
+    if ($width -lt 1) {
+      $compact = ("  {0:F1} MB" -f ($bytes / 1MB))
+      $length = [Math]::Min($compact.Length, [Math]::Max(0, $columns - 3))
+      [Console]::Error.Write(("`r$esc[2K" + $compact.Substring(0, $length)))
+      return
+    }
+    $filled = [int][Math]::Floor($percent * $width / 100)
     $bar = ([string][char]0x25A0) * $filled
-    $rest = ([string][char]0x00B7) * (32 - $filled)
+    $rest = ([string][char]0x00B7) * ($width - $filled)

Addressed the outside-diff PowerShell width finding in 68823e3efd. The bar shrinks to the terminal width, size counters are omitted when they would wrap, and very narrow or unknown-length downloads use clipped byte counts. Real PowerShell PTY checks passed at widths 1, 2, 7, 8, 9, 30, 50, 68, and 92 for known and unknown lengths. The full installer fixture passed again. The existing 92-column screenshots still show the current layout.

Keep an unknown download total unknown.

For a non-empty download without Content-Length, this call passes $bytes as $total, so Draw-Download renders a synthetic total and 100%. Pass the header value instead. Its [long] parameter maps an absent value to the existing unknown-length branch, while known lengths still render completion.

[juliusmarminge]

The final unknown-total finding is a false positive. In install.ps1, updates inside the read loop use the response Content-Length, so an unknown total stays unknown throughout the transfer. Draw-Download $bytes $bytes runs only after the stream reaches EOF successfully. At that point the received byte count is the actual completed download size, and showing 100% is intentional. This also matches the shell installer and CLI completion behavior. No code change is needed.
