v1.1.2: actually-green mipsel-softfloat (YAML comment-fold bug) (#44)

v1.1.1 still failed the mipsel CI matrix for a non-obvious reason.
The `Build CLI (mipsel-softfloat via docker)` step passed a
multi-line argument to `sh -c "..."` with `\` line continuations
and inline `#` comments:

    sh -c "set -eux; \
           # The image ships with a pre-installed nightly ... \
           rustup toolchain uninstall ... \
           ..."

YAML's `run: |` block-scalar folds that into a single line on the
shell side — backslash-newline collapses become spaces. The
payload handed to `sh -c` becomes one long line in which the
first `#` comments out everything that follows on that line, so
the only command that actually ran inside the container was
`set -eux;`. Everything after it was a comment. The container
exited successfully (set -eux + empty; is a zero-exit no-op),
the `target/` directory never got created, and the post-docker
`sudo chown -R "$(id -u):$(id -g)" target` failed with

    chown: cannot access 'target': No such file or directory
    Process completed with exit code 1.

which fooled me into thinking the toolchain logic failed, when
actually NO toolchain logic ran at all.

Fix: use bash with a single-quoted multi-line script. Single
quotes preserve newlines literally, so `#` stays a
line-terminating comment rather than collapsing. Heredoc-style
formatting; same commands as before.

No other changes. Version bumps only (Cargo + Android versionCode/
versionName). Telegram notify stays off via the repo-variable
gate we added yesterday.
