ID List Support expansion

**Scope Audited**
- Topdata configured value encoders in [native.go](/home/vicky/Projects/nwnee-shadowsoverwestgate/toolkit/internal/topdata/native.go:3894)
- Config validation in [project.go](/home/vicky/Projects/nwnee-shadowsoverwestgate/toolkit/internal/project/project.go:799)
- Wiki alignment formatting
- Module topdata config/docs and authored `PreferredAlignments` / `ProficiencyFeats` files

**Changes Made**
- Added generic `id_hex_list` support. It works for any configured dataset/column and emits packed hex row IDs from `ids`.
- Updated alignment encoding to accept explicit `alignments`; legacy `list` still works.
- Kept numeric packed lists on `list` / `all_except`.
- Configured `baseitems.ProficiencyFeats` in [nwn-tool.yaml](/home/vicky/Projects/nwnee-shadowsoverwestgate/module/nwn-tool.yaml:73).
- Migrated module proficiency authoring to `ids` and racial alignment authoring to `alignments`.
- Updated docs in [module/topdata/README.md](/home/vicky/Projects/nwnee-shadowsoverwestgate/module/topdata/README.md:157).

**Configuration / Schema Impact**
- New `topdata.value_encodings[].mode`: `id_hex_list`.
- `id_hex_list` accepts:
  - `"feat:some_key"`
  - `{ "id": "feat:some_key" }`
  - numeric IDs, still range-checked by `min`, `max`, `hex_width`.

**Compatibility Impact**
- Existing numeric packed lists are unchanged.
- Existing alignment `{ "list": [...] }` remains accepted, but docs and module data now prefer `{ "alignments": [...] }`.
- ID-list behavior is config-driven, not hardcoded to proficiencies.

**Tests Added / Updated**
- Added build test for generic `id_hex_list`.
- Added validation test for unknown ID references.
- Updated alignment tests to use `alignments`.
- Updated wiki alignment tests for explicit `alignments` plus legacy `list`.

**Validation Performed**
- `go test ./internal/topdata` passed.
- `go test ./internal/project` passed.
- `go test ./...` passed.
- `SOW_TOOLS_DEV_BINARY=../toolkit/tools/sow-toolkit ./scripts/run-nwn-tool.sh config validate` passed in `module/`.

**Remaining Risk**
- `./validate-topdata.sh` in `module/` is currently blocked by existing staged module authored-content changes: generated feat/baseitems validation reports `dataset baseitems: override must specify id or key` from `topdata/data/feat/generated`. I did not try to repair that unrelated staged work.
