feat(install): add SENTRY_INIT env var to run wizard after install

[betegon]

Summary

Lets users install the CLI and launch the setup wizard in one command:

curl -fsSL https://cli.sentry.dev/install | SENTRY_INIT=1 bash

After the normal install completes, resolves the installed binary by checking the same candidate directories as the TS code (SENTRY_INSTALL_DIR > ~/.local/bin > ~/bin > ~/.sentry/bin), then runs sentry init </dev/tty. The </dev/tty reopens stdin from the terminal since curl | bash consumes it for the pipe.

Also adds install to the docs-preview workflow path filter — changes to the install script weren't triggering preview builds because the symlink in docs/public/ doesn't match the docs/** glob.

Test plan

• curl -fsSL .../install | SENTRY_INIT=1 bash — installs CLI, then launches wizard with working interactive prompts
• curl -fsSL .../install | bash (without env var) — normal install, no wizard
• Verify binary is found even when installed to ~/.sentry/bin (fallback path)

Closes #682
