First proposal for a finalized interlinear model (#25)

* First proposal for a finalized interlinear model

* Adjusted JSDoc, made enums const

* Add charStart and charEnd to Token in order to facilitate scriptio continua

- Both are non-optional because computation is trivial and keeps our options open for user-defined token boundaries in whitespace languages if ever desired
- Updated cspell

* Remove entryIds from where it could cause problems

* `status` field now required everywhere present, local gloss now mutually exclusive with gloss/sense from lexicon extension, clarify invariance requirement for tokenSnapshots

* Convert enums to string literal unions

- `enum` values are inlined by `tsc` at compile time. The Platform.Bible build pipeline uses SWC, which processes files in isolation and cannot inline `enum` values from `.d.ts` declarations.

* Update docs to reflect new string literal union instead of enum, make it clear that we're working with UTF-16 offset units, define id scope used by flat analysis references, disambiguate morpheme-level alignment endpoints, prevent empty Phrase membership

* Revert specification of offset characters as UTF-16 code units

* Merge remote-tracking branch 'origin/main' into interlinear-model
