test(tree): Whole-document text test suite

[brrichards]

Description

Adds onto the testing suite for plain/formatted text in textDomain.integration.bench.ts. Includes helpers and setup for the 7 tests. Tests against multiple sized documents of N-character sizes. The tests include these performance and memory tests:

1. Summary size
2. Fresh document size (no edits/history)
3. Forest footprint (chunked forest)
4. full string read time
5. editing time (done in middle of the doc)
6. hydrated vs unhydrated views
7. load time from summary

Hi! Thank you for opening this PR. Want me to review it?

Based on the diff (446 lines, 1 files), I've queued these reviewers:

• Correctness — logic errors, race conditions, lifecycle issues
• Security — vulnerabilities, secret exposure, injection
• API Compatibility — breaking changes, release tags, type design
• Performance — algorithmic regressions, memory leaks
• Testing — coverage gaps, hollow tests

How this works

• Adjust the reviewer set by ticking/unticking boxes above. Reviewer toggles alone don't trigger anything.

• Tick Start review below to dispatch the review fleet.

• After review finishes, tick Start review again to request another run — it auto-resets after each dispatch.

• This comment updates as new commits land; your reviewer selections are preserved.

Would there be any value in running these benchmarks against both the optimized format and the object format?

[brrichards]

I don't see a downside. Should we complete this work - comparison forest and then use it for this scenario?
