fix(capabilities): read openclaw host-compat from package.json

[claytonlin1110]

summary

• kb.capabilities's host_compat block read openclaw.compat.pluginApi from openclaw.plugin.json, but the manifest deliberately excludes a top-level "openclaw" key (test_openclaw_plugin_manifest.py's dead-dialect-fields check, from feat(openclaw): declare vouch-context engine contract #228) — so _load_host_compat() always returned {}, unconditionally failing the two chore(release): pin pluginApi compat baseline in kb.capabilities #237 drift-detection tests on test.
• package.json is the one place openclaw.compat.pluginApi actually lives (already enforced by test_package_json_declares_entry_and_compat). Points the reader — and the mirroring test fixture in tests/test_capabilities.py — at package.json instead.
• unrelated to feat: thin-page enrichment — propose expansions for stub/sparse pages #309 / PR feat(enrich): thin-page enrichment proposes expansions for stub pages #403; spotted while running the full suite for that PR and confirmed pre-existing on a pristine upstream/test checkout.

test plan

• tests/test_capabilities.py — all pass, including the two previously-failing drift-detection tests
• tests/test_openclaw_plugin_manifest.py — still green (confirms the manifest's dead-dialect-fields invariant is untouched)
• ruff check clean
• mypy src clean (no new errors)
