feat: auto-upgrade bare lark-cli without y/N confirmation

[dc-bytedance]

Summary

Bare lark-cli invocations no longer wait for a [y/N] keypress before upgrading. When a cached newer version is detected in an interactive terminal session, the CLI now upgrades automatically.

Changes

• offerRootUpgrade prints a one-line notice and calls runRootUpgrade directly, instead of prompting and blocking on stdin.
• Removed the now-unused readYes helper and its dedicated test.
• All four existing trigger gates are unchanged: concealed-capability check, three-way TTY detection (stdin/stdout/stderr), bare-invocation detection, and cached-update presence.
• lark-cli update itself (install-method detection, binary verification, rollback, skills sync) is unmodified.

Test Plan

• Unit tests pass (go test ./cmd/...), including updated TestOfferRootUpgrade cases covering all TTY gates, opt-out, and version-comparison branches
• Manual local verification confirms the lark-cli bare-invocation flow works as expected: in a pseudo-TTY with a cached newer version, the CLI upgrades without any keypress; with stdout/stderr redirected (non-TTY), no upgrade output appears

Walkthrough

Root upgrades now proceed automatically when a cached update is available. The interactive confirmation helper and related test cases were removed. Tests now use an empty input reader and cover terminal, cache, and opt-out states.
