ci: add rust-version MSRV policy

[KooshaPari]

User description

Adds explicit rust-version = "1.75" MSRV policy to Cargo.toml.

---

Note

Low Risk
Low risk: only adds metadata to enforce a minimum Rust toolchain version; no runtime or behavior changes.

Overview
Sets an explicit workspace MSRV by adding rust-version = "1.75" under [workspace.package] in Cargo.toml, allowing tooling/CI to enforce a consistent minimum Rust compiler version.

• Builds and checks can now fail earlier when run with an older Rust toolchain

Impact

✅ Fewer build failures from unsupported Rust versions
✅ Clearer toolchain requirements for contributors
✅ More consistent CI checks

MSRV 1.75 contradicts edition 2024 and resolver 3

High Severity

The newly declared rust-version = "1.75" is incompatible with the workspace's own resolver = "3" (requires Rust 1.84+) and all member crates' edition = "2024" (requires Rust 1.85+). This MSRV is unreachable — Cargo on Rust 1.75 cannot process this workspace at all. The rust-version value needs to be at least "1.85".

🟠 Architect Review — HIGH

The declared MSRV rust-version = "1.75" is incompatible with all workspace crates, which are configured with edition = "2024" and therefore require a newer Rust compiler than 1.75; this advertises an MSRV that cannot successfully build the code.

Suggestion: Update rust-version to the true minimum Rust version that supports edition 2024 (and the current dependency set), and enforce it in CI by running builds/tests on that exact toolchain.

This is an **Architect / Logical Review** comment left during a code review. These reviews are first-class, important findings — not optional suggestions. Do NOT dismiss this as a 'big architectural change' just because the title says architect review; most of these can be resolved with a small, localized fix once the intent is understood.

	*HIGH: The declared MSRV `rust-version = "1.75"` is incompatible with all workspace crates, which are configured with `edition = "2024"` and therefore require a newer Rust compiler than 1.75; this advertises an MSRV that cannot successfully build the code.

Validate the correctness of the flagged issue. If correct, How can I resolve this? If you propose a fix, implement it and please make it concise.
If a suggested approach is provided above, use it as the authoritative instruction. If no explicit code suggestion is given, you MUST still draft and apply your own minimal, localized fix — do not punt back with 'no suggestion provided, review manually'. Keep the change as small as possible: add a guard clause, gate on a loading state, reorder an await, wrap in a conditional, etc. Do not refactor surrounding code or expand scope beyond the finding.
Once fix is implemented, also check other comments on the same PR, and ask user if the user wants to fix the rest of the comments as well. if said yes, then fetch all the comments validate the correctness and implement a minimal fix
