Lisa v0.26.1

Lisa v0.26.1

The v0.26.0 DMG. v0.26.0 is the release that makes Lisa.app self-contained,
and its Mac job failed before producing a disk image — so it shipped the CLI
bundles with the one asset it was about missing. Same contents, plus the
one-character fix that lets the DMG build.

🔧 embed-runtime.sh under a UTF-8 locale

The release job died at embed-runtime.sh: line 124: tarball<U+2026>: unbound variable. Under a UTF-8 locale, bash 3.2 — still /bin/bash on macOS, GitHub
runners included — swallows the bytes of a following multibyte character into an
identifier, so "$tarball…" expands a variable named tarball plus the
ellipsis, which is unset, and set -u aborts:

LC_ALL=en_US.UTF-8 bash -uc 'v=x; echo "$v…"'   # -> v…: unbound variable
LC_ALL=C           bash -uc 'v=x; echo "$v…"'   # -> fine

Note the direction — the UTF-8 locale is the one that breaks. Every local
run and every bash 5 passes, which is why this only ever surfaced on the
tag-triggered release job, running for the first time now that there is
something to embed.

Braced, and the tree swept for the same shape: it was the only occurrence.
Verified end to end under LC_ALL=en_US.UTF-8, the exact locale CI uses.
