fix(ci): preserve vendor/aqua-registry/ in PPA publish workflow

[jdx]

Summary

• cargo vendor deletes the target directory's contents by default, which was wiping out the git-tracked vendor/aqua-registry/ directory (containing registry.yml, metadata.json, LICENSE).
• build.rs reads vendor/aqua-registry/registry.yml at compile time (added in #9535), so the source tarball uploaded to Launchpad was missing this file and the build failed with No such file or directory at build.rs:357.
• Adding --no-delete to cargo vendor preserves the existing directory while still vendoring Rust crates alongside it.

Observed failure: Launchpad build log for mise_2026.5.6~resolute1.

Test plan

• Re-run the ppa-publish workflow manually and confirm vendor/aqua-registry/registry.yml is present in the uploaded source tarball.
• Confirm the resulting Launchpad build succeeds.

Note

Low Risk
Low risk CI-only change that alters cargo vendor behavior during packaging; main risk is unexpected differences in the vendored directory contents affecting reproducibility.

Overview
Updates the ppa-publish GitHub Actions workflow to run cargo vendor with --no-delete, preventing it from wiping the git-tracked vendor/aqua-registry/ directory needed at build time.

Adds brief inline comments documenting why the flag is required; all other packaging steps remain unchanged.

Greptile Summary

This one-line fix adds --no-delete to the cargo vendor invocation in the PPA publish workflow, preventing it from wiping the git-tracked vendor/aqua-registry/ directory that build.rs reads at compile time.

• The root cause (missing registry.yml causing a build failure on Launchpad) is well-understood and directly addressed by the flag.
• --no-delete may leave stale vendored crates behind if a dependency is removed, but the downstream --frozen Cargo flag ensures the lockfile is enforced, so orphaned directories are benign.

Confidence Score: 5/5

Safe to merge — a targeted, single-flag change that directly addresses a confirmed Launchpad build failure with no side effects on the Rust vendoring integrity.

The change is a single flag addition to cargo vendor. The flag's behavior is well-documented, the problem it fixes is confirmed by an actual Launchpad build log, and the rest of the workflow (checksum clearing, --frozen enforcement) is unaffected.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/ppa-publish.yml	Adds --no-delete to cargo vendor so the pre-existing vendor/aqua-registry/ directory (required by build.rs at compile time) is not wiped before the source tarball is packaged for Launchpad.
