Roadmap: #30, M1 Stack + naming, slice "rename with aliases".

What changed

• src/leo.js exports Model, List, Component; LEOObject, LEOList, LEOElement stay as deprecated aliases (same classes, so instanceof and subclassing keep working).
• readme.template uses the new names and notes the aliases; README and dist/ regenerated (npm run dist). Examples keep the old names on purpose (alias coverage) and their built bundles were rebuilt.

Tests (written first)

tests/unit/aliases_tests.js: new names exported, aliases are strictly equal to the new names, List instanceof Model. Failed 3/3 before the change.

Mutation evidence

• Removed the alias export: alias identity test fails (1 failing).
• Removed the new-name export: all 3 new tests fail.
• Restored: 55 passing.

Checks run locally

npm test (55 pass), npm run dist, npm run build:examples && npm run test:examples passed.

Pending (rest of M1)

TypeScript move, tsup/Vite, Vitest, automatic JSX runtime, drop polyfills and committed dist. No size or performance numbers claimed.

Reviewer verdict: ready (head 7be0e3f; builder revision not stated on the PR).

• CI: both test checks SUCCESS; mergeable CLEAN, base master.
• Local: npm test 55 passing at this head.
• Mutation spot-check: removing the deprecated alias export makes the alias identity test fail (54 pass, 1 fail); restored, 55 pass.
• Scope: first unchecked milestone M1 (rename with aliases). Model/List/Component exported, LEOObject/LEOList/LEOElement kept as same-class deprecated aliases, no removal, no release/version change, no perf or size claims. Docs/README and committed dist regenerated per current policy.
• Gaps: none blocking. Remaining M1 items (TS, tsup/Vite, Vitest, JSX runtime, drop dist) stay pending, so M1 is not checked.
