Fix lint issues from community plugin review

Address the source-code issues flagged by the Obsidian community plugin
review tool (https://community.obsidian.md/account/plugins/co-intelligence):

- Add `App.commands` module augmentation so `executeCommandById` is typed
  rather than an unsafe-any call.
- Cast `processFrontMatter` callbacks to `CoiNoteFrontmatter` (with
  `linked-tags` added to the type) instead of indexing `any` frontmatter.
- Derive provider name in model-service from the registered `Model.provider`
  rather than introspecting the SDK's `LanguageModel.provider`, and type the
  `generateText` params via `Parameters<typeof generateText>[0]`.
- Type the regex `replace` callback args in ChatInterface and notes.ts.
- Drop the dead `triggerChange` prop from UserInput and its call site.
- Rename unused params with `_` prefix and configure
  `@typescript-eslint/no-unused-vars` with `argsIgnorePattern: "^_"`.
- Replace `document.createElementNS`/`createElement` and `el.createEl("div")`
  with Obsidian's `createSvg`, `createDiv`, `createSpan` helpers in settings
  and the suggestion modals.
- Narrow `state.state?.file` from `any` before passing to a string parameter,
  and capture `this.app` outside the monkey-patched closure.
