Closes 2 review findings in nats/src/options.rs.

Draft — this is a starting point, not a finished change. The fix required judgment, so read it before trusting it.

# Fix confidence Finding Location
1 🟢 95 high kv.rs uses std::u32::MAX (deprecated path) which triggers a compiler warning under RUSTFLAGS=-D warnings nats/src/options.rs:105
2 🔴 10 low — review closely This is the upstream nats.rs repo consumed by the flamingo-stack fork used in OpenFrame's desktop client nats/src/options.rs:1

What changed — and what was deliberately left — is explained per finding as inline review comments on the lines each finding touched.

Merging this PR is recorded as acceptance of the rule that produced it;
closing it unmerged is recorded as rejection. Both feed rule health, so
closing a wrong suggestion is useful rather than merely tidy.

🦩 🔴 kv.rs uses std::u32::MAX (deprecated path) which triggers a compiler warning under RUSTFLAGS=-D warnings

In the backoff function (nats/src/options.rs), replaced the deprecated std::u32::MAX path with u32::MAX in the .unwrap_or(...) call, eliminating the deprecation warning that would fail the build under RUSTFLAGS="-D warnings". This is a mechanical, behavior-preserving substitution since both paths refer to the identical constant.

In nats/src/options.rs around line 105, review and complete this code-review fix: kv.rs uses std::u32::MAX (deprecated path) which triggers a compiler warning under RUSTFLAGS=-D warnings.
What the draft fix changed: In the `backoff` function (nats/src/options.rs), replaced the deprecated `std::u32::MAX` path with `u32::MAX` in the `.unwrap_or(...)` call, eliminating the deprecation warning that would fail the build under `RUSTFLAGS="-D warnings"`. This is a mechanical, behavior-preserving substitution since both paths refer to the identical constant.
Verify the change is correct and complete; do not refactor unrelated code.

🦩 🔵 This is the upstream nats.rs repo consumed by the flamingo-stack fork used in OpenFrame's desktop client

No code change was made for this finding since it is an informational cross-repo-drift observation about a fork-specific auth_url_callback feature that is not present anywhere in this file's current content, and this file's copyright header (the cited evidence) is not something that should be altered as part of a "minimal, safe fix." Confirming or restoring auth_url_callback would require adding new API surface (a new field on Options, a builder method, and integration into the connection/reconnect logic) spanning this file and others (e.g., the WebSocket connection handling), which is architectural and out of scope for a single-file, finding-driven fix. A human maintainer must verify against the actual flamingo-stack/nats.rs fork's main branch whether this construct still exists; no safe minimal edit to options.rs alone can resolve this.

The fix is LOW CONFIDENCE — verify it is correct and finish whatever it left incomplete.
