Rewrite `hugo mod npm pack` to use npm workspaces. Module deps are now
written to packages/hugoautogen/package.json and the root package.json
gets a "workspaces" reference. A hugo_packagemeta.json sidecar stores a
hash of all input package files so regular commands can warn when npm
deps are out of sync.
Other changes:
- Workspace glob patterns (*, **, {a,b}) are resolved via gobwas/glob.
- Workspaces defined in package.hugo.json are supported.
- package.hugo.json is only recognised at module roots, not in workspaces.
- When package.hugo.json exists, package.json is not mounted or vendored.
- packages/hugoautogen is not mounted or vendored from dependencies.
- Add usePackageJSON import option (auto/always/never) to control whether
a module's npm deps are included. "auto" checks for Hugo config files
or package.hugo.json.
- The staleness check is skipped when running `hugo mod npm pack` itself.

Use blobless git clone (--filter=blob:none --no-checkout) to fetch
commit history for content from Git modules, then map it using the
existing gitmap library. Cloned repos are cached in the modulegitinfo file cache.
Closes#14431Fixes#5533
This adds a new file cache named 'modulequeries' with a 24h maxAge
that caches JSON responses from 'go mod download -json' when querying
module versions with constraints (e.g., version = "<v3.0.0").
On subsequent builds, if the cached JSON exists and the module
directory it references is non-empty, the cached result is used
directly, skipping the costly VCS interaction entirely.
Fixes#14417
Go's stdlid now has a maps package, which is very useful. We have been using imports on the form `xmaps "maps"`, but auto import tools doesn't handle this, which is annoying.
I have been thinking about this for some time, but have been holding back because of all the import changes. However, now is a good time to do this, with very little unmerged code.
It was accidentally introduced because we compile it to file mounts, and `lang` on file mounts is deprecated in favor of `sites.matrix`.
But contentDir per language is something we have had for a long time, and is to useful too to deprecate.
Fixes#14287
For this and similar mounts in a theme:
```toml
[[module.mounts]]
source = 'node_modules/bootstrap'
target = 'assets/vendor/bootstrap'
```
We first check the theme itself, then the project root.
For backwards compatibility, we also make any `../../node_modules/...` `source` paths into `node_modules/...` paths when defined in themes/modules.
Fixes#14089
The old setup tried to log >= warning to stderr, the rest to stdout.
However, that logic was flawed, so warnings ended up in stdout, which makes `hugo list all` etc. hard to reason about from scripts.
This commit fixes this by making all logging (info, warn, error) log to stderr and let stdout be reserved for program output.
Fixes#13074
Replace some of the stderr output from the Go command to match the Hugo commands needed:
```
go: creating new go.mod: module github.com/bep/foo
hugo: to add module requirements and sums:
hugo mod tidy
```
See #11458
There are some breaking changes in this commit, see #11455.

This fixes a set of bugs (see issue list) and it is also paying some technical debt accumulated over the years. We now build with Staticcheck enabled in the CI build.
The performance should be about the same as before for regular sized Hugo sites, but it should perform and scale much better to larger data sets, as objects that uses lots of memory (e.g. rendered Markdown, big JSON files read into maps with transform.Unmarshal etc.) will now get automatically garbage collected if needed. Performance on partial rebuilds when running the server in fast render mode should be the same, but the change detection should be much more accurate.
A list of the notable new features:
* A new dependency tracker that covers (almost) all of Hugo's API and is used to do fine grained partial rebuilds when running the server.
* A new and simpler tree document store which allows fast lookups and prefix-walking in all dimensions (e.g. language) concurrently.
* You can now configure an upper memory limit allowing for much larger data sets and/or running on lower specced PCs.
We have lifted the "no resources in sub folders" restriction for branch bundles (e.g. sections).
Memory Limit
* Hugos will, by default, set aside a quarter of the total system memory, but you can set this via the OS environment variable HUGO_MEMORYLIMIT (in gigabytes). This is backed by a partitioned LRU cache used throughout Hugo. A cache that gets dynamically resized in low memory situations, allowing Go's Garbage Collector to free the memory.
New Dependency Tracker: Hugo has had a rule based coarse grained approach to server rebuilds that has worked mostly pretty well, but there have been some surprises (e.g. stale content). This is now revamped with a new dependency tracker that can quickly calculate the delta given a changed resource (e.g. a content file, template, JS file etc.). This handles transitive relations, e.g. $page -> js.Build -> JS import, or $page1.Content -> render hook -> site.GetPage -> $page2.Title, or $page1.Content -> shortcode -> partial -> site.RegularPages -> $page2.Content -> shortcode ..., and should also handle changes to aggregated values (e.g. site.Lastmod) effectively.
This covers all of Hugo's API with 2 known exceptions (a list that may not be fully exhaustive):
Changes to files loaded with template func os.ReadFile may not be handled correctly. We recommend loading resources with resources.Get
Changes to Hugo objects (e.g. Page) passed in the template context to lang.Translate may not be detected correctly. We recommend having simple i18n templates without too much data context passed in other than simple types such as strings and numbers.
Note that the cachebuster configuration (when A changes then rebuild B) works well with the above, but we recommend that you revise that configuration, as it in most situations should not be needed. One example where it is still needed is with TailwindCSS and using changes to hugo_stats.json to trigger new CSS rebuilds.
Document Store: Previously, a little simplified, we split the document store (where we store pages and resources) in a tree per language. This worked pretty well, but the structure made some operations harder than they needed to be. We have now restructured it into one Radix tree for all languages. Internally the language is considered to be a dimension of that tree, and the tree can be viewed in all dimensions concurrently. This makes some operations re. language simpler (e.g. finding translations is just a slice range), but the idea is that it should also be relatively inexpensive to add more dimensions if needed (e.g. role).

A common pattern for Tailwind 3 is to mount that file to get it on the server watch list.
A common pattern is also to add hugo_stats.json to .gitignore.
This has meant that the first time you start the server (no hugo_stats.json), it just doesn't work as expected.
Fixes#11264
Primary motivation is documentation, but it will also hopefully simplify the code.
Also,
* Lower case the default output format names; this is in line with the custom ones (map keys) and how
it's treated all the places. This avoids doing `stringds.EqualFold` everywhere.
