Subject: [PATCH 1/2] fix(core): map ./tracing subpath to dist/tracing/index
 explicitly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

tracing is the package's first directory module. The wildcard exports
entry ("./*" -> "./dist/*.js") substitutes the subpath literally with
no directory-index fallback, so '@ambarltd/core/tracing' resolved to the
non-existent dist/tracing.js and failed with MODULE_NOT_FOUND in
consumers — while './tracing/opentelemetry' happened to work. Caught
before 0.1.17 was published.

Verified against the built package: with the explicit entry,
require.resolve('@ambarltd/core/tracing') -> dist/tracing/index.js and
existing wildcard subpaths (e.g. ./router) still resolve.

Subject: [PATCH 2/2] rework: promote tracing facade to file-module instead of
 exports entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the special-case exports entry and instead match the package's
module convention: every public module is a top-level file resolved by
the single "./*" wildcard (future, router, json/schema, ...). The
facade moves from src/tracing/index.ts to src/tracing.ts and the
tracing/ directory keeps the implementations (opentelemetry, proxy,
simple) — the same shape as the json/ namespace. Public import paths
are unchanged: '@ambarltd/core/tracing' and
'@ambarltd/core/tracing/opentelemetry' both resolve.

Verified: tsc build clean, require.resolve OK for tracing,
tracing/opentelemetry and router against the built package, typecheck
clean, 123/123 core tests pass.
