Pin Go version in mise.toml

What & why

Pins Go 1.26.6 in the repository's mise.toml.

Without a repository-local Go version, running Go commands through Mise could fail with:

mise ERROR No version is set for shim: go
Set a global default version with one of the following:
mise use -g [email protected]
mise use -g [email protected]

This was encountered when running:

go build -o ./bin/compozy .

Adding Go to [tools] ensures contributors using Mise get the expected Go version from the repository configuration instead of requiring a global Mise configuration.

How you verified it

Re-ran:

go build -o ./bin/compozy .

after adding:

go = "1.26.6"

to mise.toml.

Mise now resolves the repository-local Go version instead of failing with No version is set for shim: go, allowing the build to proceed.

No tests were added because this change only fixes the development toolchain configuration and does not introduce or modify application behavior.

Impact

No runtime, CLI interface, HTTP/UDS route, config.toml, or web surface impact.

This only affects local development environments using Mise by ensuring the Go toolchain is configured by the repository.

No documentation update is required.

• make gate passes locally (make gate-full before review on larger changes)
• New or changed behavior is covered by tests, or I explained above why not
• If an agent wrote or co-wrote this, I named it above and verified the result myself
