Summary

pnpm build failed with exit code 1: the slides and backend package
builds errored on missing exports.

slides:  @wafflebase/docs has no exported member 'detectUnit' / 'getGridConfig'
         / 'drawTicks' / 'RulerUnit' / 'GridConfig' / 'TickDensity'
backend: @wafflebase/slides has no exported member 'Guide';
         'guides' does not exist on type 'SlidesDocument'

Root cause — these symbols were added in #285 (slides ruler + guides) and
are correctly exported from source, but cross-package type resolution reads each
dependency's built dist/*.d.ts (gitignored, often stale), not its source. The
root build script (a) never built @wafflebase/docs at all, and (b) ran every
package build concurrently with no dependency ordering, so slides compiled
against docs' stale dist and backend against slides' stale dist.

Dependency graph:

docs    (leaf)
sheets  (leaf)
slides   -> docs
frontend -> docs, sheets, slides
backend  -> docs, sheets, slides
cli      -> docs, slides

Fix — build in topological order: (docs, sheets) -> slides -> (frontend, backend, cli), so every package compiles against freshly built
dependency declarations.

Test plan

• rm -rf packages/*/dist && pnpm build → exit 0 (was exit 1 before, from a clean dist state)
• pnpm verify:fast → exit 0 (792 tests pass)
