Fix collapsed dock wrapping

[bjufre]

Problem

Long single-line process output can make the collapsed log dock hit the terminal right edge. In the screenshot, the dock row containing the CI URL is the pi-processes-owned part of the layout.

Before screenshot:

Scope note

The repeated loading/thinking rows above the dock are rendered by Pi core, not pi-processes. This PR does not claim to fix that part directly. It only removes right-edge pressure from the collapsed dock so the dock is not the source of terminal wrapping/overpaint at the bottom of the layout. If the loading rows still duplicate/misplace without dock wrapping, that likely needs a separate Pi TUI/core fix.

Cause

The collapsed dock padded rows to the full terminal width. That is risky at the terminal right edge when logs contain very long unbroken strings such as CI URLs.

Fix

• Reserve one right-edge terminal column in collapsed dock rows.
• Centralize collapsed-row truncation/padding in renderCollapsedDockLine.
• Keep open dock rendering unchanged.
• Add regression coverage for long CircleCI-style log lines, ANSI-styled lines, and narrow widths.

Verification

• Confirmed latest upstream/published version is v0.9.1; no released fix present.
• pnpm vitest run src/components/log-dock-component.test.ts
• pnpm test
• pnpm typecheck
• pnpm lint

ah shit, sorry about that, let me test this

Looks good. This fixes the regression from collapsed dock rows filling the terminal width after the panel helper restore.\n\nChecked diff and ran:\n- pnpm test\n- pnpm typecheck\n- pnpm lint\n\nThe one-column reserve is scoped to collapsed dock rows and tests cover long unbroken URLs, ANSI-styled content, and narrow widths.
