docs(agent): queue live ISO hardware findings

Record the Acer Aspire install and session feedback as separate NOW items #91-#99, with the literal (none) XKB build blocker first and acceptance criteria for each issue.

Verified: V0 — source screenshots reviewed and git diff --check passed. Implementation verification remains item-specific.

+- **Task:** Transcribe Bernardo's Acer Aspire M5-481T install/session notes
+  and installer failure photo into the executable queue.
+- **Did:** Added nine separate NOW items: literal `(none)` XKB install
+  failure, keyboard/swap installer clarity, missing browser, Ghostty launch,
+  charge-threshold discoverability, BlueZ failure, Boreal button contrast,
+  and the false-looking untracked-theme warning.
+- **Verified:** V0 — exact backlog IDs/content reviewed; Nix failure's first
+  causal error preserved separately from cascading dependency failures;
+  `git diff --check` green.
+- **Pending:** implementation and item-specific V1–V3 verification.
+- **Next suggestion:** #91 — fix the installation-blocking keyboard variant.
