Oxlint and oxfmt toolchains

[AleksanderEvensen]

Adds the oxc toolchain formatter and linter as toolchain addons in the cli.

Note: This PR depends on TanStack/config#342. I can change the dependency on @tanstack/oxlint-config if it's preferred not to use unmerged packages.

Ran this branch locally and there is one hard blocker before merge: generated apps cannot install because @tanstack/oxlint-config@^0.1.0 is not published on npm (E404). Repro: scaffold with --toolchain oxlint then run npm install in the generated app.

Suggested fix: remove dependency on unpublished @tanstack/oxlint-config for now (use an inline/default oxlint config), then we can follow up to switch once the package is published.

Everything else looks directionally good and the toolchain scaffolding appears in both React and Solid.

Follow-up: given the current install blocker ( is not published), this PR should be reopened only with either (a) a passing setup that removes the unpublished dependency, or (b) a concrete publication plan/timeline for and updated dependency/versioning to match. Closing for now to keep main mergeable.

Correction: the missing package is @tanstack/oxlint-config. Please reopen only with either (1) a passing setup that removes this unpublished dependency, or (2) a concrete publish plan/timeline for @tanstack/oxlint-config plus updated dependency/versioning once available.
