feat(cli): update version command and add version tag to init (#1820)

## Summary
- Updates the version command to display in the format `v1.3.0-rc.1
(abc123...)` instead of showing build timestamp
- Adds version tag to openvm dependency when running `cargo openvm init`
- Dependencies now include `tag = "v1.3.0-rc.1"` for reproducible builds

## Changes
1. Modified `OPENVM_VERSION_MESSAGE` in `crates/cli/src/lib.rs` to show
version and commit hash
2. Updated `crates/cli/build.rs` to only emit git SHA (removed build
timestamp)
3. Enhanced `add_openvm_dependency` function in
`crates/cli/src/commands/init.rs` to include version tag

## Test plan
- [x] Built cargo-openvm with `cargo build -p cargo-openvm`
- [x] Tested version command: `./target/debug/cargo-openvm openvm
--version` outputs `v1.3.0-rc.1 (46160dd)`
- [x] Tested init command: `cargo openvm init` now adds dependency with
version tag
