Change

Implement syntax-extensions (spec-driven). All 55/55 tasks complete.

Complete

Export extension types; register prop, class-name, and element constants.
Resolve aliases independent of entry/array order; preserve single-entry alias scope.
Reject reserved built-in roots, duplicate keys, missing targets, alias cycles.
Longest plain-dot matching; scope shadowing; constant-call and unresolved-path diagnostics.
Preserve predefined content order, class fallback, caller arguments on void elements.
Use shared runtime attribute replacement/removal and class accumulation semantics.
Pass extensions through unplugin pre-scan and Babel transform.
Document configuration, constraints, ordering, user-managed declarations.

Verification

bun run test: 375 pass, 0 fail.
bun run check: all workspace typechecks pass.
bun run lint: 0 errors, 51 warnings.
git diff --check: clean.
openspec instructions apply --change syntax-extensions --json: all_done, 55/55.
openspec validate syntax-extensions: valid, no header-mismatch warnings. Both MODIFIED headers now match main specs.
openspec validate --all: 36 pass, 5 unrelated changes fail (client-lifecycle-hooks, css-value-helpers, extended-style-attribute, factory-components, ref-tag-name-generic). Left unchanged.
No archive attempted.
Bun emits directory-mismatch diagnostic during test startup; suites exit successfully.

Planning Artifacts

Approved example corrections, completed task tracking, and header fixes saved locally in linked planning repository; not included in this code-repository PR. Built-in CSS roots container and d replaced by custom example identifiers panel and divAlias; class strings retained. Stale thunk examples corrected to direct arguments.
