v0.8.0.4 — take the test server's name back out of the tracked files

Both repositories allow anonymous clone — checked rather than assumed: info/refs
for git-upload-pack answers 200 for each, git-receive-pack answers 401. So
everything committed here is public, and tracked files are supposed to carry
placeholders rather than real hosts.

Ten mentions added while building v0.8.0 are now "the test server" or "the target
hardware", across CHANGELOG.md, the common-board plan's three deferral banners,
sim/pacing.ts, and two test files. Prose and comments only, no behaviour; the
quotes are untouched, because what was said about bot pacing is the part worth
keeping.

Left alone deliberately: nineteen older mentions in entries about v0.7.5, v0.7.6
and v0.7.8 and in TODO.md, since rewriting a changelog after the fact makes the
record less true; and scripts/deploy-web.ts, where the host is the functional
default for FB_URL rather than prose — turning that into a required variable
changes how deploying works and wants deciding on its own.
