Update npm dependencies to latest

[gtritchie]

Updates all devDependencies to their latest versions, with one held back, and adapts the source to the two major bumps (TypeScript 6, Obsidian 1.13.0 typings).

Version changes

Package	From	To
@types/node	25.5.0	25.9.1
esbuild	0.27.5	0.28.0
jiti	2.6.1	2.7.0
obsidian	1.12.3	1.13.0
typescript	5.8.3	6.0.3
typescript-eslint	8.58.0	8.60.0
@eslint/js	9.39.4	held

@eslint/js stays on 9.x because eslint-plugin-obsidianmd@0.3.0 peer-pins @eslint/js: "^9.30.1"; moving to the ESLint 10 ecosystem would break that peer dependency.

Source changes required by the major bumps

• tsconfig: TypeScript 6 turns baseUrl and moduleResolution: "node" (node10) into hard errors. Removed the unused baseUrl (all imports are relative) and switched moduleResolution to "bundler", which matches the esbuild/ESNext setup.
• main.ts: Obsidian 1.13.0 adds Plugin.settings?: unknown as a base member. Changed settings!: to declare settings: to refine the inherited type, per the typings' own guidance.
• settings.ts: PluginSettingTab.display() now requires an override modifier. Internal re-renders route through a new rerender() helper holding a single justified @typescript-eslint/no-deprecated suppression; the imperative settings API remains fully supported and is retained intentionally.
• confirm-modal.ts / remove-selection-property.ts: kept setWarning() (with a justified suppression) rather than setDestructive(), which would require raising minAppVersion from 1.8.7 to 1.13.0.

minAppVersion is unchanged at 1.8.7.

Verification

• npm run build (tsc type-check + esbuild production) passes
• npm run lint exits clean
• npm install reports 0 vulnerabilities
• Manual smoke test in Obsidian: settings add/remove re-render, settings persistence, warning buttons, and an end-to-end bulk edit all work
