fix(ci): add electron-rebuild step to Linux release build

[jschwxrz]

summary:

• fixes PTY unavailable error on Linux since 0.4.16 (NODE_MODULE_VERSION 127 vs. 123

cause:

• native modules (node-pty, sqlite3, keytar) are compiled for CI runners node 22 (ABI 127)
• those modules need to be recompiled for electrons node version (ABI 123)
• in 0.4.15, postinstall script handled this rebuild, but was changed to be skipped in CI in 0.4.16 (mac build needs to be per architecture, postinstall could not handle that)
• each platform is now expected to run "electron-rebuild" explicitly in the workflow
• mac and windows already had that step, linux was still missing it

fix:

• added electron-rebuild step for linux

fixes #1068

Greptile Summary

This PR fixes the "PTY unavailable" error on Linux builds since version 0.4.16 by adding the missing electron-rebuild step to the Linux release workflow. Native modules (node-pty, sqlite3, keytar) are compiled for Node.js 22 (ABI 127) during CI install, but need to be recompiled for Electron's Node.js version (ABI 123).

The postinstall script that previously handled this rebuild was changed in 0.4.16 to skip execution in CI environments because Mac builds require per-architecture rebuilds. Mac and Windows workflows were already updated with explicit electron-rebuild steps, but Linux was missed.

Changes:

• Added electron-rebuild step before Linux package build
• Command matches Mac/Windows patterns: rebuilds for x64 architecture with explicit Electron version
• Targets the same three native modules: sqlite3, node-pty, keytar

Confidence Score: 5/5

• Safe to merge - minimal change that fixes a critical Linux runtime error
• The fix is a straightforward addition of a missing build step that already exists in the Mac and Windows workflows. The command syntax, module list, and architecture all match the established pattern. This directly addresses issue [bug]: critical: Github Copilot Chat UI does not work anymore since 0.4.16 #1068 with a well-understood root cause.
• No files require special attention
