perf(sdk): split twenty-sdk barrel into per-purpose subpaths to cut logic-function bundle ~700x (#19834)
## Summary

Logic-function bundles produced by the twenty-sdk CLI were ~1.18 MB even
for a one-line handler. Root cause: the SDK shipped as a single bundled
barrel (`twenty-sdk` → `dist/index.mjs`) that co-mingled server-side
definition factories with the front-component runtime, validation (zod),
and React. With no `\"sideEffects\"` declaration on the SDK package,
esbuild had to assume every module-level statement could have side
effects and refused to drop unused code.

This PR restructures the SDK so consumers' bundlers can tree-shake at
the leaf level:

- **Reorganized SDK source.** All server-side definition factories now
  live under `src/sdk/define/` (agents, application, fields,
  logic-functions, objects, page-layouts, roles, skills, views,
  navigation-menu-items, etc.). All front-component runtime
  (components, hooks, host APIs, command primitives) lives under
  `src/sdk/front-component/`. The legacy bare `src/sdk/index.ts` is
  removed; the bare `twenty-sdk` entry no longer exists.

- **Split the build configs by purpose / runtime env.** Replaced
  `vite.config.sdk.ts` with two purpose-specific configs:
  - `vite.config.define.ts` — node target, externals from package
    `dependencies`, emits to `dist/define/**`
  - `vite.config.front-component.ts` — browser/React target, emits to
    `dist/front-component/**`
  Both use `preserveModules: true` so each leaf ships as its own `.mjs`.

- **\`\"sideEffects\": false\`** on `twenty-sdk` so esbuild can drop
  unreferenced re-exports.

- **\`package.json\` exports + \`typesVersions\`** updated: dropped the
bare \`.\` entry, added \`./front-component\`, and pointed \`./define\`
  at the new per-module dist layout.

- **Migrated every internal/example/community app** to the new subpath
  imports (`twenty-sdk/define`, `twenty-sdk/front-component`,
  `twenty-sdk/ui`).

- **Added \`bundle-investigation\` internal app** that reproduces the
  bundle bloat and demonstrates the fix.

- Cleaned up dead \`twenty-sdk/dist/sdk/...\` references in the
  front-component story builder, the call-recording app, and the SDK
  tsconfig.

## Bundle size impact

Measured with esbuild using the same options as the SDK CLI
(\`packages/twenty-apps/internal/bundle-investigation\`):

| Variant | Imports | Before | After |
| ----------------------- |
------------------------------------------------------- | ---------- |
--------- |
| \`01-bare\` | \`defineLogicFunction\` from \`twenty-sdk/define\` |
1177 KB | **1.6 KB** |
| \`02-with-sdk-client\` | + \`CoreApiClient\` from
\`twenty-client-sdk/core\` | 1177 KB | **1.9 KB** |
| \`03-fetch-issues\` | + GitHub GraphQL fetch + JWT signing + 2
mutations | 1181 KB | **5.8 KB** |
| \`05-via-define-subpath\` | same as \`01\`, via the public subpath |
1177 KB | **1.7 KB** |

That's a ~735× reduction on the bare baseline. Knock-on benefits for
Lambda warm + cold starts, S3 upload size, and \`/tmp\` disk usage in
warm containers.

## Test plan

- [x] \`npx nx run twenty-sdk:build\` succeeds
- [x] \`npx nx run twenty-sdk:typecheck\` passes
- [x] \`npx nx run twenty-sdk:test:unit\` passes (31 files / 257 tests)
- [x] \`npx nx run-many -t typecheck
--projects=twenty-front,twenty-server,twenty-front-component-renderer,twenty-sdk,twenty-shared,bundle-investigation\`
passes
- [x] \`node
packages/twenty-apps/internal/bundle-investigation/scripts/build-variants.mjs\`
produces the sizes above
- [ ] CI green
