ci(mobile-verify): broaden path filter to cover real mobile deps

The initial filter only watched `apps/mobile/**` and
`packages/core/types/**`, but mobile imports runtime modules from many
more `@multica/core/*` paths (agents, markdown, permissions,
api/schemas, etc.). PRs that touched only those subtrees would skip
main CI (via `--filter='!@multica/mobile'`) AND skip Mobile Verify — a
coverage regression vs. the pre-split CI.

Expand paths to:
- `packages/core/**` (covers every importable subpath)
- root install/turbo configs that affect mobile build:
  `package.json`, `pnpm-lock.yaml`, `pnpm-workspace.yaml`, `turbo.json`

+# Path scope rationale — mobile transitively depends on:
+# - apps/mobile/**                — the app itself
+# - packages/core/**              — mobile imports types AND pure functions

+#                                   not only @multica/core/types
+# - package.json / pnpm-lock.yaml — install graph
+# - pnpm-workspace.yaml           — catalog versions
+# - turbo.json                    — turbo task pipeline

+# Mobile has no vitest suite today; if one lands, add `test` to the turbo
+# task list below.
