kingwl aebf9c863b feat(cli): launch dsh source through the tsx ESM hook
Node 26.0.0 removed --experimental-transform-types, so the native
source-launch chain cannot start anywhere on that line, and strip-only
mode rejects the vendored syntax (parameter properties, decorators,
runtime enums/namespaces). Switch bin/dsh, the root dsh/demo:tui/
demo:web scripts, and the Code Mode TUI overlay to node --import
tsx/esm: one launch vector across the whole engines range, ~0.4s faster
than the full tsx default (the CJS hook stays off; the graph is
ESM-only).

Delete scripts/tspath-loader.ts and apps/cli/src/tsconfig-paths-loader.ts:
tsx owns both transformation and tsconfig paths projection. Add
dsh-source-launch-smoke to the node-compat gates so the 22.19/26 matrix
executes the real launch vector; no CI job did, which is how the Node 26
breakage shipped silently.

Supersedes the native-TypeScript-source-launch Agent Note (new note
records the profiling evidence and rejected alternatives).

# The ESM-only tsx hook transforms TypeScript and projects this checkout's
# tsconfig paths into Node resolution (the CJS hook stays off: the graph is
# ESM-only and the CJS resolver costs ~0.4s of startup). Absolute paths keep
# both the hook and the tsconfig anchored to this checkout when the launcher
# runs from any cwd, where bare `tsx/esm` would not resolve.
