## Prompt
Task Objective: Compute multi-dimensional aggregation metrics from the user open-start-path detail table, outputting UV and first-time UV across three dimension combinations: application category (`referer_type`), source application (`referer`), and launch path (`path`).

Inputs:
- `internal_platform_db.t_ed_mapservice_user_open_start_path_dwd_di_query_engine_135`
- `internal_platform_db.t_ed_mapservice_user_q36_active_dwd_di_query_engine_135`

Processing Rules:
1. Main table filter: `ds=20260608`, and `referer` must be in the specified lists of application package names/keys for three categories (FoodChainA, QuickDog, JD).
2. Path cleansing: Process the `path` field according to rules — if it matches `qqmap://map/routeplan?type=\w+`, retain the original value; if it contains `?`, truncate to the part before the question mark; if it is empty/null/`'NULL'`, set it to `'未知'`; otherwise, retain the original value.
3. `referer_type` mapping: Map the `referer` value to one of three categories: `'FoodChainA'`, `'CourierCoB'` (QuickDog), or `'EcommerceC'` (JD).
4. Join: Join with `t_ed_mapservice_user_q36_active_dwd_di_query_engine_135` (`ds=20260608`, `uin` deduplicated) on `uin`, retaining active users.
5. Aggregation: Group by `referer_type`, `CUBE(referer, path)`, computing `count(distinct uin)` as `uv` and `count(distinct case when is_first=1 then uin end)` as `first_uv`.
6. CUBE result processing: For dimensions where `grouping` is 1, set the value to `'total'`.

Output Requirements:
- Field order: `referer_type`, `referer`, `path`, `uv`, `first_uv`, `ds`
- `referer` and `path` display as `'total'` on CUBE summary rows
- `uv` is of type BIGINT, `first_uv` is of type BIGINT

Write Requirements:
- Output table: `internal_platform_db.t_md_mapservice_user_open_start_path_dwa_di_cand_query_engine_135`
- Partition: `ds=20260608`
- Write method: `INSERT OVERWRITE`

Please write the final HiveSQL to `result.sql` and execute it.
