[Bug] Sandbox initialization fails on Linux: missing apply-seccomp helper in v2.1.98+

Bug Description
---
Title: Sandbox failed to initialize on Linux with bwrap 0.11.0 (v2.1.98+)

Description:

All bash commands fail with "Sandbox failed to initialize" on v2.1.98 and v2.1.100 native installs on Linux. Even echo test fails.
Rolling back to v2.1.97 fixes it.

Environment:

• OS: Linux 6.12 (Debian 13, amd64)
• Install: native binary at ~/.local/share/claude/versions/
• bwrap: /usr/bin/bwrap 0.11.0
• kernel.unprivileged_userns_clone = 1
• CONFIG_SECCOMP=y, CONFIG_SECCOMP_FILTER=y
• No AppArmor denials for bwrap

Root cause: apply-seccomp helper not found anywhere in the native install directory. Present in v2.1.97, missing in v2.1.98+.

Workaround: ln -sf ~/.local/share/claude/versions/2.1.97 ~/.local/bin/claude

Environment Info

• Platform: linux
• Terminal: vscode
• Version: 2.1.97
• Feedback ID: e4ee42d0-22e9-4ad8-b893-9d0c388ab6f3
