Even with ts_omit_drive, the drive package is currently still imported
for some types. So it should be light. But it was depending on the
"regexp" packge, which I'd like to remove from our minimal builds.

Fix "file not found" errors when WebDAV clients access files/dirs inside
directories with spaces.
The issue occurred because StatCache was mixing URL-escaped and
unescaped paths, causing cache key mismatches.
Specifically, StatCache.set() parsed WebDAV responses containing
URL-escaped paths (ex. "Dir%20Space/file1.txt") and stored them
alongside unescaped cache keys (ex. "Dir Space/file1.txt").
This mismatch prevented StatCache.get() from correctly determining whether
a child file existed.
See https://github.com/tailscale/tailscale/issues/13632#issuecomment-3243522449
for the full explanation of the issue.
The decision to keep all paths references unescaped inside the StatCache
is consistent with net/http.Request.URL.Path and rewrite.go (sole consumer)
Update unit test to detect this directory space mishandling.

Extract field comments from AST and include them in generated view
methods. Comments are preserved from the original struct fields to
provide documentation for the view accessors.

This adds support for having every viewer type implement
jsonv2.MarshalerTo and jsonv2.UnmarshalerFrom.
This provides a significant boost in performance
as the json package no longer needs to validate
the entirety of the JSON value outputted by MarshalJSON,
nor does it need to identify the boundaries of a JSON value
in order to call UnmarshalJSON.
For deeply nested and recursive MarshalJSON or UnmarshalJSON calls,
this can improve runtime from O(N²) to O(N).
This still references "github.com/go-json-experiment/json"
instead of the experimental "encoding/json/v2" package
now available in Go 1.25 under goexperiment.jsonv2
so that code still builds without the experiment tag.
Of note, the "github.com/go-json-experiment/json" package
aliases the standard library under the right build conditions.

Some systems have `sudo`, some have `su`. This tries both, increasing
the chance that we can run the file server as an unprivileged user.

Instead of calculating the PeerAPI URL at the time that we add the peer,
we now calculate it on every access to the peer. This way, if we
initially did not have a shared address family with the peer, but
later do, this allows us to access the peer at that point. This
follows the pattern from other places where we access the peer API,
which also calculate the URL on an as-needed basis.
Additionally, we now show peers as not Available when we can't get
a peer API URL.
Lastly, this moves some of the more frequent verbose Taildrive logging
from [v1] to [v2] level.

Fix the index out of bound panic when a request is made to the local
fileserver mux with a valid secret-token, but missing share name.
Example error:
http: panic serving 127.0.0.1:40974: runtime error: slice bounds out of range [2:1]
Additionally, we document the edge case behavior of utilities that
this fileserver mux depends on.

Clients often perform a PROPFIND for the parent directory before
performing PROPFIND for specific children within that directory.
The PROPFIND for the parent directory is usually done at depth 1,
meaning that we already have information for all of the children.
By immediately adding that to the cache, we save a roundtrip to
the remote peer on the PROPFIND for the specific child.

This improves convenience and security.
* Convenience - no need to see nodes that can't share anything with you.
* Security - malicious nodes can't expose shares to peers that aren't
allowed to access their shares.
