Full Release Notes

This release brings a couple of nice quality-of-life improvements alongside several bug fixes.

### Highlights

**Shell-style variable expansion in env values** ([#8029](https://github.com/jdx/mise/pull/8029)) - You can now use shell-style variable expansion like `${VAR:-default}` and `${VAR:+alternate}` directly in your `mise.toml` environment variables. This makes it easier to set up flexible configurations without needing to drop into shell scripts.

**New `--all-sources` flag for `mise ls`** ([#8019](https://github.com/jdx/mise/pull/8019)) - Thanks to @TylerHillery for adding this flag, which shows all the sources where a tool version is defined. Useful for debugging why a particular version is being used when you have multiple config files.

### Bug Fixes

- **gem backend**: Fixed Windows support and resolved a newline issue in gem scripts ([#8031](https://github.com/jdx/mise/pull/8031), [#8034](https://github.com/jdx/mise/pull/8034)) - Thanks @my1e5!
- **lockfile**: Tools are now written to the lockfile matching their source config, fixing issues where lockfile entries could get misattributed ([#8012](https://github.com/jdx/mise/pull/8012))
- **mise ls**: Sources in `--all-sources` output are now sorted deterministically ([#8037](https://github.com/jdx/mise/pull/8037))
- **tasks**: File tasks now auto-install tools defined in `mise.toml`, matching the behavior of inline tasks ([#8030](https://github.com/jdx/mise/pull/8030))

### Security

- Updated the `time` crate to 0.3.47 to address RUSTSEC-2026-0009 ([#8026](https://github.com/jdx/mise/pull/8026))
