refactor(params)!: flatten [params.page] to [params], snake_case keys, more page-level params support (#805)

* refactor(params)!: snake_case config + eliminate params.page + use .Param BREAKING CHANGE: All params keys renamed from camelCase to snake_case, [params.page] section eliminated (moved to [params] level), and users must update their hugo.toml and front matter accordingly. Key changes: - All camelCase config keys → snake_case (e.g., defaultTheme → default_theme) - [params.page] flat keys and sub-sections moved to [params] level - Removed function/params.html (manual merge), replaced with Hugo .Param - New function/param.html partial for page-level section params with shorthand boolean support and site defaults merging - New function/camel-case.html for string conversion - snake2camel.html renamed to camel-case-keys.html - New function/get-cover.html for cover image resolution - Deprecation warnings in detection-deprecated.html for old config keys - Front matter only params (subtitle, featured_image, password, repost, weight, message) use .Params.xxx instead of .Param - Page-level sections use param.html partial - Simplified patch.html (siteTime only) and init/index.html Refs: camel-case-keys.html#29 (planned v1.0 breaking change) * refactor(params)!: move params.link to page-level, simplify link guard - Move [params.link] and [params.link.guard] to page-level section - link.html: .Page optional, use param.html when available for page-level override, fall back to site config without .Page - Remove $guardConfig variable, use $config.guard directly - Remove unnecessary .Page from callers that don't need page override - friends.html: use param.html for link guard instead of link_guard * refactor(params)!: move image/codeblock/json_viewer/filetree to page-level - Move [params.image], [params.codeblock], [params.json_viewer], [params.filetree] to page-level sub-sections - Templates use param.html for merged config (page override + site defaults) - image.html: .Page optional, falls back to site config without .Page - Add v1- prefix to all deprecation warnidf IDs - Fix camelCase key access in image.html (blackList, cacheRemote) - Fix Hugo-lowered camelCase keys in code-block-wrapper.html - Add deprecation warnings for codeblock camelCase Markdown attributes - Add deprecation warnings for file-tree camelCase Markdown attributes - Update render-codeblock-toggle.html for snake_case attribute names * style: standardize @param comment style across all HTML templates - PascalCase types: {string} → {String}, {boolean} → {Boolean}, {int} → {Int}, {map} → {Map}, {array} → {Array} - Add missing ` - ` separator between param name and description - Remove extra alignment spaces between type and param name * refactor(params)!: move params.mermaid to page-level, extract gen/ templates - Move [params.mermaid] to page-level sub-sections - Mermaid config injected into window.config (per-page override support) - mermaid.ts reads config from window.config.mermaid instead of parameter - Create _partials/gen/ directory for JS content generators - Move mermaid-bootstrap.html from plugin/ to gen/ - Extract window.config JS generation into gen/config.html - mermaid.html uses param.html for wrapper config * refactor(params)!: consolidate link_to_* into params.post_link section - Move link_to_markdown/source/edit/report/vscode into [params.post_link] - Rename keys: markdown, source, edit, report (bool), editor (string) - editor defaults to "vscode", supports "trae" etc. via protocol template - footer.html uses .Param "post_link" for all link toggles - Remove link_to_* from deprecated keys list * fix: add fallback for deprecated camelCase attributes and expand deprecation warnings - render-codeblock-file-tree.html: folderSlash attribute fallback - render-codeblock-toggle.html: lineNosToggler/lineWrapToggler fallback + warnings - code-block-wrapper.html: maxShownLines/wrapperClass fallback - detection-deprecated.html: add nested key warnings for 13 sections (header, breadcrumb, navigation, watermark, busuanzi, image, mermaid, codeblock, filetree, math.katex, math.mathjax.options, post_summary, footer) - detection-deprecated.html: add link_guard front matter deprecation warning * fix(mermaid): fix rendering in hidden tab panels and neutral layer scheduling - isRenderContextActive: check tab-panel visibility via getBoundingClientRect instead of panel.hidden (tab-container uses slot-based hiding, not hidden attr) - bindTabContainerChanged: render neutral layers when switching tabs so print/fallback scenarios work correctly

-The image plugin is a partial that handles image resources.
+{{- /*
+  Image resource plugin.
+  Handles page resources, global resources, and remote images.
+  Supports optimisation, srcset generation, black list filtering, and remote caching.

-Parameters:
- Src: The path to the image. 
-    It can be a page resource (inside a page bundle) https://gohugo.io/methods/page/resources/
-    or a global resource (inside the assets directory) https://gohugo.io/functions/resources/get/
-    or a link to a remote resource, which can be cached if the site parameter is set https://gohugo.io/functions/resources/getremote/
- Resources: If the image is a page resource, this parameter is required. It is the .Resources of the page.
- OptimConfig: optimisation parameter, defined like 
-    {{- $optim := slice 
-        (dict "Process" "resize 800x Center webp q75" "descriptor" "800w")
-        (dict "Process" "resize 1200x Center webp q75" "descriptor" "1200w")
-        (dict "Process" "resize 1600x Center webp q75" "descriptor" "1600w")
-    -}}
-    See https://gohugo.io/content-management/image-processing/ for more information.
- Alt: alt text for the image. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#alt
- Height: The intrinsic height of the image, in pixels. Must be an integer without a unit.
-    We try to generate this value automatically if possible. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#height
- Width: The intrinsic width of the image, in pixels. Must be an integer without a unit.
-    We try to generate this value automatically if possible. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#width
- Loading: Indicates how the browser should load the image: eager or lazy. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#loading
- Optimise: Override the site parameter to optimise the image.
- CacheRemote: Override the site parameter to cache remote images.
- BlackList: A list of image file names or patterns to exclude from optimisation, default is from site parameter.
- Matches: If the image is a page resource, this parameter can help to find the resource by names. e.g. ["featured-image", "featured-image-preview"].
+  Pass .Page when the caller needs page-level config override (e.g., content images).
+  Omit .Page for decorative/site-level images (e.g., logos, avatars, badges).
