feat: auto-install validate skill and logger hook on startup

On every `InstanceBootstrap` (TUI session start), automatically:
- Copy `SKILL.md` + `batch_validate.py` → `~/.claude/skills/validate/`
- Write `altimate_logger_hook.py` → `~/.claude/hooks/` and merge Stop hook
  into `~/.claude/settings.json` (skipped if `ALTIMATE_LOGGER_DISABLED=true`)

The logger hook reads the session JSONL transcript after each assistant
response and posts the conversation turn to `/log-conversation` in the
same payload format as `conversation-logger.ts`.

Removed `validate install` from `bun run build` — no manual setup needed.
Uses `globalThis` lookup for build-time globals so dev mode (`bun run dev`)
falls back to reading files directly from disk.
