Environment variables in [env] block not accessible in templates with env or get_env

[bartsmykla]

Describe the bug
I'm trying to rewrite some of our Make targets to use Mise tasks, but I'm having trouble with environment variables. It doesn't matter if I set the variable explicitly in the [env] block in the config file, specify it via a .env file set in env._.file, or export it in a shell file specified in env._.source. The issue is the same. I can't access the variable in templates using the env object or the get_env function. However, if I use the same variable as a bash variable (like $FOO) in a task, it works without any issues.

To Reproduce

Example 1: task

# mise.toml
min_version = "2024.12.14"

[env]
VERSION_CONTROLLER_GEN = "{{ exec(command='go list -f {{.Version}} -m sigs.k8s.io/controller-tools') }}"
BAR = "bar"

[tasks.bar]
run = """
echo '{{ env.BAR }} {{ get_env(name="BAR") }}'
echo '{{ env.VERSION_CONTROLLER_GEN }} {{ get_env(name="VERSION_CONTROLLER_GEN") }}'
"""

Result of mise run bar:

panic in task: panicked at src/task/task_script_parser.rs:280:54:
called `Result::unwrap()` on an `Err` value: Error { kind: Msg("Failed to render '__tera_one_off'"), source: Some(Error { kind: Msg("Variable `env.BAR` not found in context while rendering '__tera_one_off'"), source: None }) }

Example 2: tool version

min_version = "2024.12.14"

[env]
VERSION_CONTROLLER_GEN = "{{ exec(command='go list -f {{.Version}} -m sigs.k8s.io/controller-tools') }}"

[tools]
controller-gen = "{{ env.VERSION_CONTROLLER_GEN }}"

In this situation mise is broken and even mise doctor returns

mise ERROR failed to parse template {{ env.VERSION_CONTROLLER_GEN }} in ~/project/mise.toml
mise ERROR Failed to render '__tera_one_off'
mise ERROR Variable `env.VERSION_CONTROLLER_GEN` not found in context while rendering '__tera_one_off'
mise ERROR Run with --verbose or MISE_VERBOSE=1 for more information

Expected behavior

Variables set in the [env] block, a .env file (using env._.file), or a shell file (using env._.source) should be available in templates. They should work with the env object and the get_env function, no matter how they are defined.
