In @.github/workflows/docs-links-pr.yaml:
- Line 35: The current population of md_files captures all changed *.md
including vendored/generated paths; update the mapfile command that sets
md_files to exclude common non-doc directories by filtering out patterns like
node_modules, dist, vendor, build (e.g., modify the git diff pipeline that
produces md_files or append a grep -v -E '^(node_modules|dist|vendor|build)/'
before the sort) so md_files only contains real documentation markdown changes.

Nitpick comments:
In `@test/e2e/e2e-cloud-experimental/check-docs.sh`:
- Around line 224-230: The fenced-code detection only toggles for backticks (the
Perl one-liner in check-docs.sh that currently uses if (/^\s*```/) to flip $in),
so add tilde fence support by changing that condition to match either ``` or ~~~
(i.e., update the Perl fence-toggle regex inside the extract/processing
one-liner to /^\s*(```|~~~)/ so links inside ~~~ blocks are skipped as well).

- Around line 224-225: Replace the permissive fence-toggle logic in the perl
one-liner (the /^\s*(```|~~~)/ branch that flips $in) with a delimiter-aware
handler: detect fence openings via /^\s*(`{3,}|~{3,})/ and record the fence
character and length into $fch and $flen when entering ($in=1), and only exit
the fence (set $in=0 and clear $fch/$flen) when a closing fence uses the same
character and length >= $flen; update the assignments/tuples that set ($in,
$fch, $flen) accordingly so the link-scanning next/while blocks remain gated by
the refined $in state.

In `@test/e2e/e2e-cloud-experimental/check-docs.sh`:
- Around line 225-235: The fence-closing check using the regex
/^\s*(`{3,}|~{3,})/ incorrectly treats lines like "```not-a-close" as closes;
update the logic in the block that uses the regex and variables ($in, $fch,
$flen) so that a closing fence is only accepted if the matched fence is followed
only by optional whitespace (i.e., nothing else on the line). Concretely, either
change the regex to assert end-of-line or only whitespace after the marker, or
after matching check the remainder of the line for non-whitespace characters
before flipping ($in, $fch, $flen) to close the fence.
