chore(actions): move cache and artifact actions onto Node 24

[kevinccbsg]

GitHub is deprecating Node 20 on Actions runners. actions/cache, actions/upload-artifact and actions/download-artifact were all pinned to v4, which declares using: node20, so every consumer of the run and record actions gets a deprecation annotation on an otherwise green run.

The Node 24 default landed in a different major for each action, so this takes each to its current release rather than a uniform version:

action	before	after	Node 24 since
actions/cache	v4	v6.1.0	v5
actions/upload-artifact	v4	v7.0.1	v6
actions/download-artifact	v4	v8.0.1	v7

Applied to both composite actions (run, record) and to e2e.yml. Everything stays SHA-pinned, and runs.using: node24 was verified on each new SHA.

Why the artifact round-trip still works

• upload v7 adds archive: false for single-file direct uploads. Both call sites pass a directory, so the default (archive: true) keeps the existing zip behaviour.
• download v8 skips unzipping non-zipped payloads by checking Content-Type. Our uploads are still zips, so they unzip as before.
• The merge job's pattern: twd-run-* download still produces the per-shard directory layout twd-cli merge expects.
• download v8 now errors rather than warns on a digest mismatch. That is the behaviour we want.

Consumer note

upload-artifact v6+ and download-artifact v7+ require Actions Runner 2.327.1 or newer. GitHub-hosted runners are well past that; anyone invoking the run or record action on self-hosted runners needs to be current.
