fix: simple ESLint errors — regex, unused vars, unused expressions

- eslint.config.js: ignore coverage/ directory (generated files)
- frontmatter.ts: no-regex-spaces — use {2} instead of literal spaces
- wikilinks.ts: no-useless-escape — remove unnecessary \[ escape
- ai-chat.ts: remove unused _model param from getContextLimit
- noteListHelpers.ts: remove unused _modifiedFiles param from filterEntries
- NoteList.tsx: replace ternary expression statement with if/else
- useTabManagement.ts: remove stale eslint-disable-next-line comment
