fix: stage publish dir mirroring repo layout so dist/ ships in package

[gueritopollito]

Problem

v1.0.3 published successfully but the package is empty of JavaScript — installing it fails with extension entry not found: ./dist/index.js.

Root cause: the workflow publishes from inside dist/, but package.json declares files: ["dist", ...], main: dist/index.js, and openclaw extensions: ["./dist/index.js"]. Relative to dist/ as package root, there is no dist/ subdirectory — so npm packed only package.json, README, LICENSE, openclaw.plugin.json, and skills/. Same broken layout went to ClawHub.

(The manual 0.1.0 publish worked because it ran from the repo root.)

Fix

Stage a pack/ directory that mirrors the repo layout — dist/ as a subdirectory alongside package.json, skills/, etc. — and run semantic-release + ClawHub publish from there. Also strips prepublishOnly/prebuild from the staged package.json (CI already builds and tests; those hooks assume full repo layout).

Verified locally with npm pack --dry-run from a staged dir: tarball now contains dist/index.js and all compiled output at the correct paths.

Notes

• v1.0.3 is burned on NPM; this will release as v1.0.4
• scripts/ no longer needs to be copied (hooks that needed it are stripped)

Test plan

• Merge, verify v1.0.4 releases to NPM + ClawHub
• openclaw plugins install clawhub:@expediagroup/expedia-openclaw succeeds
