- Replace single-assignment `let timer` with a `timers[]` array in
citrine.ts and relayProbe.ts so stricter prefer-const builds pass
(the newer ESLint pulled in by `npm audit fix` flagged the let as
never-reassigned).
- Drop two now-redundant `eslint-disable react-hooks/exhaustive-deps`
directives in NostrProvider and MapPage. Newer react-hooks no longer
reports those lines, so the directives were flagged as unused errors
under reportUnusedDisableDirectives; removing them is safe in both
old (warning only) and new (silent) ESLint.
