Adds ESM boundary declarations to every workspace package manifest
(apps/server, packages/core, extensions/example): "type": "module",
"main"/"types" entry points and an "exports" map (types + import
conditions) so each package exposes only its public root; adds
"type": "module" to the workspace root package.json so the workspace is
uniformly ESM. Placeholder src/index.ts files stay as empty ESM modules.
Verified: each package compiles under tsconfig.base.json (NodeNext) with
TypeScript 6.0.3 and emits ESM dist/index.js + dist/index.d.ts; Node
imports each package by name through its exports map and rejects deep
subpath imports (ERR_PACKAGE_PATH_NOT_EXPORTED); pnpm 11.23.0
install --frozen-lockfile passes with the lockfile unchanged.
Closes#156
Adds a strict base TypeScript config at the workspace root (ES2023 / NodeNext
/ strict family incl. noUncheckedIndexedAccess, exactOptionalPropertyTypes,
noImplicitOverride, useUnknownInCatchVariables, verbatimModuleSyntax per
Engineering-Standards) and gives every workspace package
(apps/server, packages/core, extensions/example) a tsconfig.json that extends
it. Each package gets a minimal src/index.ts placeholder so it compiles under
the base config (CJS-safe `export {}` until ESM boundaries land in T03).
Verified: every package typechecks and emits (js + d.ts + sourcemap) with the
pinned TypeScript 6.0.3; a strictness probe confirms the strict family fires.
Closes#155
