The prior null-safe esc patch only matched 'const esc =' declarations;
Menu/Navbar/Logo use 'function esc(str: string)' syntax and slipped
through. Patched those three to coerce non-strings the same way.
Added "Clear chat" button in the modal header that appears when there's
any message history. Confirms with the user before posting to the new
clear_history endpoint, which deletes all messages + the thread row
for the current site (usage rows are preserved for billing).
Real-world AI output frequently sends mismatched prop names (e.g.
items vs features, cta object vs buttonText/Href). The toHtml functions
of section/form/sections-folder components each defined a local
esc = (s: string) => s.replace(...) that crashed when called with
undefined, taking the auto-save export with it.
Patched every local esc() to coerce non-strings:
const esc = (s: any) => String(s ?? "").replace(...)
17 files touched; behavior unchanged for valid string inputs.
Also adds a WorkingIndicator (Claude Code-style spinner + rotating
phrase + elapsed seconds) shown in the modal footer while a generation
is in flight, replacing the disabled "Thinking..." placeholder.
