refactor(ve2): retire per-family state contracts for the literal ones

[rhengles]

The dropdownItemActive report is right about the facts and wrong about the
cause. The four contracts were not forgotten — they are the unwired remainder
of a whole category.

A per-family alias collapses a compound source selector into one identifier:
.dropdown-item.active → dropdownItemActive, .btn.show → btnShowHook.
33 identifiers stood for 9 Bootstrap state classes. The literal emitter
translates 1:1, so each alias needed a divergence-manifest entry to exist in
the CSS at all — 12 remapSymbols plus 8 mirrors, hand-written, one per family
that happened to have a component demanding it. Families without a demo never
got an entry, so 18 of the 33 shipped with no CSS behind them. Nothing
compared the two hand-maintained lists.

Emitting both (the report's first suggestion) is the addMirrorRule pattern
that already produced 8 of those entries; it would take the list from 15 to 19
and keep the failure mode. An alias is a pure rename — ${navLink}${active}
has identical specificity and match set — so it buys no isolation the compound
selector doesn't already give. Plan §8.6 said this; T8 reverted it on the
wrong side by teaching the emitter to produce the aliases instead of
regenerating the CSS.

• divergence manifest 22 → 2 entries (body-split, legend-element-mirror)
• 36 contracts deleted: the 33 aliases, tooltipVe/popoverVe, and the duplicate
  fade/show/collapse copies in ui/navs, ui/modal, ui/navbar. literal/ is now
  the single owner of every shared state token.
• kept modalOpenHook and carouselSlide: .modal-open and .slide have no
  rule in any bootstrap.css, so they are runtime markers, not aliases
• 27 themes regenerated onto ${component}${state}: −4290 lines, the per-family
  .fade / .fade:not(.show) mirrors collapse into one generic rule each
• 8 adapters + ~90 components stamp the literal hashes, dropping the
  double-stamp workarounds that had accumulated in 58 files

Gate: check-contract-wiring.mjs (static, pre-build) plus a liveness assertion
in build-contract.mjs (authoritative, real hashes vs emitted CSS). It keys on
(module, symbol), not name — fade is declared twice and a name-keyed check
reads the live copy as proof the dead one is fine. Deliberate inertness goes
in contract-wiring-allowlist.mjs with a reason; a state hook never qualifies.

Two further bugs the gate surfaced: build-contract only checked liveness for
duplicate candidates, so a name declared by exactly one module was published
unchecked — the precise mechanism that shipped the four; and contractModules()
filtered by filename, excluding layout/container.css.ts, so containerFluid
resolved to literal's dead copy while the themes styled layout's.

Also regenerates theme-runtime.ts, which still imported the utilities/used
family retired in dd753ef — ve-project2 did not build without it.

Package dead exports 90 → 68, all allowlisted. active keeps hash b17c3vgbe3.
Verified by rule-set equivalence across all 27 themes: 0 distinct rules
dropped, 0 added (scripts/_cssdiff.mjs).

BREAKING CHANGE: dropdownItemActive, listGroupItemActive, navLinkActive
and the other per-family state aliases are gone. Compose the literal contract
instead: cx(dropdownItem, isActive && active), with active from the
package's global entry. The removed names now fail to compile rather than
failing to paint.
