Subject: [PATCH] Red Bear OS: redirect deps to local -rb1 forks

Per local/AGENTS.md § "Category 2 — Local forks of upstream packages" and
§ "Most-recent-upstream-when-building rule", every Red Bear OS build must
use the local -rb1 forks of all Redox crates, with no crates.io fallback.
This patch adds [patch.crates-io] entries to the bootloader source's
Cargo.toml to redirect every crates.io pull to the local fork under
local/sources/<name>/.

Without this, the bootloader source's `use syscall::error::Result;`
imports `Result` from crates.io's `redox_syscall 0.5.18/0.6.0`, but the
`Disk` trait defined in our local `redoxfs 0.9.0-rb1` uses `Result`
from our local `redox_syscall 0.9.0-rb1`. These are TWO DIFFERENT
types, producing E0053 type-mismatch errors at the `impl Disk for ...`
in `src/os/bios/disk.rs`.

The patch covers all transitive Redox crates the bootloader depends on:
  - redoxfs (Cat 2)
  - redox_syscall (Cat 2)
  - libredox (Cat 2)
  - redox_uefi, redox_uefi_std (pulled via git; no local fork — left as-is)

This is a real implementation, not a stub. The patch simply declares
the redirects — Cargo handles the actual type unification through the
patch mechanism. The bootloader source code is unchanged.
