fix: clear remaining `npm run check` errors (12 → 0)

Three groups of errors blocking the global typecheck:

A. Announce morfo used invalid family/intent vocabulary
   - `absent-clear` event used `family: 'absent'` and `intent: 'absent'`,
     neither valid in current MorfoEventSemantic schema
   - Renamed to `commit-reset` (family: commit, verb: reset, intent: neutral)
     matching SearchField's clear-reset pattern
   - Updated demo copy to reference the new event name
   - Cascade-resolved 4 errors (morfo + soma provider + demo + active-uix test)

B. Tree wrappers stripped bindable props
   - eidos `<TreeGrid>` didn't expose `expanded`/`value` as `$bindable`;
     they leaked through `...rest` and Svelte rejected `bind:expanded`
   - Same issue for `<TreeView>` with `expandedValue`/`selectedValue`
   - Now declared explicitly + forwarded via `bind:` to soma's Provider

C. Virtual containers passed wide `style` to native markup
   - `style` was typed `string | Record<string, unknown> | null | undefined`
     but the markup `<div style={...}>` only accepts string
   - Filtered with `typeof style === 'string'` derived guard before render

svelte-check result: 5076 files, 0 errors, 23 warnings (no-op warnings
in navigation-menu `href="#"` and table `state_referenced_locally`).
