fix(tui): cap session-title length at 32 chars

Resolve #128

Problem

See linked issue. On Windows Terminal the session title written by Kimi Code can stretch the tab bar past readable width — at the current 80-character cap, CJK content reaches ~160 terminal columns and ASCII content shows the entire first user message inline.

This PR addresses the tab-width side of the report. The second concern in the issue — pasted code is unreadable as a title regardless of length — is not addressed here; both suggested directions in the issue (skip the OSC title override entirely, or summarize the first message via the model) are larger behavior changes that benefit from maintainer input first.

What changed

MAX_PROCESS_TITLE_LENGTH is lowered from 80 to 32 in apps/kimi-code/src/tui/constant/terminal.ts. The slicing in setProcessTitle (apps/kimi-code/src/tui/utils/proctitle.ts) already honors the constant, so no other code change is required. The new cap fits typical tab widths (~20–25 visible characters in Windows Terminal / iTerm tab bars) while keeping enough context to identify the session.
