rand upgrade breaks AntithesisRng compatibility
The comment on lines 18-19 explicitly documents that rand must stay at 0.8 until antithesis_sdk upgrades its dependency — yet this PR bumps rand from 0.8.5 to 0.10.0.
In the lockfile, antithesis_sdk 0.2.8 still depends on rand 0.8.5 (and therefore rand_core 0.6). The project's rand 0.10.0 uses rand_core 0.10. These trait families are incompatible: AntithesisRng implements rand_core::RngCore from 0.6, but rand 0.10's Rng trait requires rand_core::RngCore from 0.10.
This means code like rng.gen_range(1..=record_body_budget) and rng.fill(&mut body[..]) in history.rs:50-52 (where rng is an AntithesisRng) will fail to compile, since the rand::Rng trait from 0.10 is not implemented for AntithesisRng.
This is the same incompatibility that led to commit 64bd89e ("rollback rand version"), which rolled rand back from 0.9.2 to 0.8.5 and added this exact comment.

**`rand` upgrade breaks `AntithesisRng` compatibility**
The comment on lines 18-19 explicitly documents that `rand` must stay at 0.8 until `antithesis_sdk` upgrades its dependency — yet this PR bumps `rand` from `0.8.5` to `0.10.0`.
In the lockfile, `antithesis_sdk 0.2.8` still depends on `rand 0.8.5` (and therefore `rand_core 0.6`). The project's `rand 0.10.0` uses `rand_core 0.10`. These trait families are incompatible: `AntithesisRng` implements `rand_core::RngCore` from `0.6`, but `rand 0.10`'s `Rng` trait requires `rand_core::RngCore` from `0.10`.
This means code like `rng.gen_range(1..=record_body_budget)` and `rng.fill(&mut body[..])` in `history.rs:50-52` (where `rng` is an `AntithesisRng`) will fail to compile, since the `rand::Rng` trait from `0.10` is not implemented for `AntithesisRng`.
This is the same incompatibility that led to commit `64bd89e` ("rollback rand version"), which rolled `rand` back from `0.9.2` to `0.8.5` and added this exact comment.
