fix: apply wizard personality picker and identity persistence

[escapables]

Summary

• Fix personality picker in TUI apply wizard ignoring user selection
• Restore companion name/personality after binary re-patch (e.g. after Claude Code updates)

Bug 1: Personality picker ignores selection

src/tui/apply/index.ts:589 read activeSelect.selectedIndex — a setter-only property on OpenTUI's SelectRenderable with no corresponding getter. Reading it returns undefined, not the current index.

Since values[undefined] is undefined, the choice never matched 'keep' or 'default', falling through to the custom-input prompt. Pressing Enter without typing left personality unchanged.

Fix

- const idx = activeSelect.selectedIndex;
+ const idx = activeSelect.getSelectedIndex();

Bug 2: Name/personality lost after re-patch

After a Claude Code update resets the binary, the SessionStart hook (apply --silent) re-patches the salt but never restores the companion's custom name and personality from the saved profile. Claude Code regenerates the companion with defaults, and the user's choices are lost.

Fix

Added restoreProfileIdentity() in src/tui/commands/apply.ts — after every successful patch or salt verification, reads the active profile and writes name/personality back to the Claude config. Fails silently if the companion hasn't been hatched yet.

Test plan

• pnpm run typecheck — pass
• pnpm run lint — pass
• pnpm run test — 203/203 pass
• Manual test: applied a new buddy, confirmed personality selection works and persists
