Replace hand-rolled regex heuristic with proper acorn JS parsing.
The AST correctly identifies ExpressionStatement as the last node
regardless of trailing semicolons, comments, or complex syntax.
Fixes edge cases like '42;' which the regex wrongly treated as a
statement.

Stdio handshake:
Server now sends { type: register, token } to WebSocket clients on
connection, so the stdio bridge receives the token immediately instead
of deadlocking while both sides wait to receive.
Eval return values (REPL-style):
Add wrapEvalCode() that detects when the last non-empty line is a value
expression and promotes it to a return statement. Bare expressions like
JSON.stringify(result) now return the value instead of undefined.
Single implementation in packages/core/src/tools/analyze/eval-wrap.ts
used by both the tool and the automation bridge.
