Fix ZFS boot failure: set cachefile property after pool creation

- Add zpool set cachefile=/etc/zfs/zpool.cache after pool creation
- Without this, initramfs ZFS hook can't import pool at boot
- Causes "cannot import '(null)': no such pool available" error
- Add cachefile property test to full-test.sh

 #+TITLE: Session Context
 #+DATE: 2026-01-20
 
-* Previous Session: Monday 2026-01-20
-
-** Completed
-
-*** Fixed hostid mismatch bug (commit 0524467)
-- Root cause: ~hostid~ command returned value X, then ~zgenhostid~ created /etc/hostid with value Y
-- Fix: Call ~zgenhostid~ FIRST in configure_bootloader(), then read consistent value
-- Verified: GRUB and /etc/hostid match after installation
-
-*** Added Avahi mDNS to installed systems (commit f62bf9b)
-- Packages: avahi, nss-mdns added to pacstrap
-- Service: avahi-daemon enabled
-- Matches archsetup implementation
-- Systems now accessible as <hostname>.local after install
-
-*** Added Avahi validation to test scripts (commit 7b6c409)
-- sanity-test.sh: Check avahi-daemon enabled and running
-- test-install.sh: Verify packages and service on installed system
-
-*** Fixed full-test.sh bug (commit a774bae)
-- Bug: ((TESTS_PASSED++)) returns exit code 1 when starting at 0
-- Fix: Use pre-increment ((++TESTS_PASSED))
-
-** Test Results
-- Sanity test: 15/15 passed
-- Single-disk install: PASS
-- Mirror install: PASS
-- RAIDZ1 install: PASS
-
-** ISO Distributed
-- ~/Downloads/isos/
-- truenas.local:/mnt/vault/isos/
-- /dev/sda (ARCHZFS USB boot drive)
-- /dev/sdb1 (Ventoy)
-
-** Notes
-- ratio needs reinstall with fixed ISO (or manual hostid fix)
