Lint (eslint.config.js)

• Rewrite on defineConfig/globalIgnores with one shared rule set.
• ESM files see only Node built-in globals; .cjs files get CommonJS globals. Tests and bin/ are now linted.
• Fix no-unused-vars so unused arguments are reported; parameters kept for arity use a leading "_".
• TypeScript uses typescript-eslint strictTypeChecked and stylisticTypeChecked with projectService.
• Enforce private-member conventions: no "#_x", no TS private modifier, no leading-underscore members (Node stream hooks exempt).

Formatting

• Add Prettier 3.9.10 (.prettierrc.json, .prettierignore): tabs, double quotes, semicolons, 120 columns, chosen as the lowest-churn options.
• Remove the unused .prettierrc.cjs and reformat all JS/TS sources.

Source idioms

• "#_x" -> "#x" in lib/; TS private -> "#" in src/cli/.
• var -> const/let, Object.hasOwn, Number.isNaN/Number.isFinite, for...of Object.entries, arrow functions in place of .bind(this), and object spread in place of Object.assign({}, ...).
• PDFParser._PARSER_SIG keeps its public name for back-compat and now reads the shared PARSER_SIG from lib/pkinfo.js.

TypeScript

• Upgrade 5.9.3 -> 6.0.3; typescript-eslint supports TS <6.1.
• tsconfig: module/moduleResolution nodenext, target/lib es2024, verbatimModuleSyntax, erasableSyntaxOnly, noImplicitOverride.
• Type the CLI's PDFParser members and settle-result types (type-only changes).

Scripts and CI

• Add lint:fix, format, format:check and typecheck scripts. The build now runs lint, format check and typecheck before bundling.
• CI: run on push to master, bump action majors, Deno 2.9.8, Node 22.23.2, add typecheck and format-check steps, and add a non-blocking TypeScript 7 typecheck.

Docs

• AGENTS.md: code-quality commands and lint-enforced conventions.
• readme: lint/format/typecheck section; build-before-test note replaces the removed pretest step; the command-line test section now uses the real p2j.*.sh scripts and npm run test:forms/test:misc; the exception-test counts are now 22 files, 16 pass, 6 expected failures, with the current file names.
