feat(mise): configure default tools as lazy

[jdx]

Summary

• add the mise-tool contribution skill and convert every Omarchy-managed tool to a registry shorthand
• declare the default CLI tools as native lazy tools in /etc/mise/config.toml
• collocate system and user installs/shims under ~/.local/share/mise, so first-use installs stay unprivileged
• migrate recognized legacy wrappers without touching user-owned commands, while preserving Remove/Install Preinstalls behavior
• document mise install --include-lazy for installing every lazy tool up front

Why

mise v2026.9.1 now provides native lazy tool shims, system-config storage overrides, safe shim reconciliation, and mise install --include-lazy. Omarchy can use those primitives directly instead of maintaining one wrapper script per command.

Dependency

• requires mise v2026.9.1 or newer; chore(mise): bump to 2026.9.1 omarchy-pkgs#278 updates the package from mise-bin 2026.8.15 and must ship before this PR

Testing

• official mise-v2026.9.1-linux-x64 release binary: offline reshim --system created all 19 expected command shims from the system config
• official release binary: isolated mise install uv installed uv@0.12.8 from the lazy system-style config, verified its GitHub artifact attestations, and executed it through mise x
• official release binary: invoking the generated gh shim installed gh@2.98.0, verified its GitHub artifact attestations, and ran gh --version
• settings.locked=true: a system lazy shim installed and ran uv@0.12.9; mise install --include-lazy --dry-run resolved all 16 managed tools
• explicit --locked: mise install --include-lazy --dry-run resolved all 16 managed tools without requiring system lockfiles
• config-free Hermes path: installed Hermes Agent v0.19.0 through lazy uv, verified Python 3.13.15, and ran it without changing the user-global mise config
• focused lazy migration, default-agent, Hermes, Python/uv lifecycle, and preinstall shell tests
• ./test/cli
• ./test/shell completed; all changed-area tests passed. Environment-only failures were the three checks requiring a sibling omarchy-pkgs checkout and the existing roomy-window animation assertion. network-qr-test.sh also failed once in the aggregate run and passed immediately when rerun alone.

VM testing

• installed the official harness dependencies (qemu-full 11.1.0, edk2-ovmf, socat, ImageMagick, and Tesseract) and ran the VM-free omarchy-iso suite successfully
• built a 5.8 GB fresh ISO from this branch plus chore(mise): bump to 2026.9.1 omarchy-pkgs#278; the bundled offline repository contained locally built mise-bin 2026.9.1-1
• drove a real fresh install under QEMU/KVM through the configurator, package installation, reboot, console bootstrap, SDDM, and Hyprland session
• all 25 keyboard-driven desktop shortcut checks passed; the installed-system acceptance checks passed for core packages, services, applications, defaults, and session health
• inside the installed guest, /usr/bin/mise --version reported 2026.9.1, /etc/mise/config.toml was active, and the shim directory contained the 19 Omarchy lazy commands alongside the existing Node shims
• from a cold state, MISE_LOCKED=1 uv --version installed and ran uv@0.12.9 from /etc/mise/config.toml; the user's global Node declaration remained in ~/.config/mise/config.toml, and mise correctly did not require a system lockfile
• mise install --include-lazy --dry-run resolved every remaining lazy system tool in the installed guest
• reused the installed base with --sync-all and ran the PR's CLI, shell, and graphical acceptance suites in the VM; all mise/Hermes/uv tests passed. The broad run retained unrelated fixture/environment failures (missing omarchy-pkgs checkout for packaging-coverage tests, font-width/animation assertions, one privileged migration fixture) plus a reminder-panel visual timeout.

Two test-only harness accommodations were needed and were not applied to this PR: the current ISO helper does not locally build non-omarchy* packages, so the test harness was extended to build mise-bin from the supplied package checkout; and Arch's current broadcom-wl → broadcom-wl-dkms transition required a current-Arch mirror/package-list override while the Omarchy snapshot catches up. The harness's greeter OCR was also broadened to accept the current “Beautiful, Fun & Agentic” tagline.
