vasilito 068a1ca63e bootloader: rebase onto upstream 1.0.0, sync firmware-loader version
Bootloader fork rebase:
- Base changed from 0.1.0 pre-patched archive to upstream 1.0.0 tag (c7eeb9f)
- Applied 0001-redbear-local-forks.patch (Cargo.toml crate path redirects)
- Applied fix-uefi-alloc-panic.patch equivalents (4 panic!() -> graceful
  error handling in src/main.rs)
- Applied P5-live-preload-cap-1gib.patch (1 GiB cap on live image preload)
- Skipped: P0 GPT partition scan (requires new module + integration),
  P1 timeout/default-resolution, P2 live preload guard (subsumed by
  panic fixes + cap), P3 live image safe read, P4 large ISO boot,
  redox.patch — to be applied in dedicated rebase session.

firmware-loader/Cargo.toml: version 0.1.0 -> 0.3.0 (sync with other
Red Bear custom crates which are at 0.3.0).

fork-upstream-map.toml: bootloader back from PENDING_REBASE to 1.0.0
since the partial rebase matches upstream 1.0.0 content.

fork-upstream-map.toml: base restored to 'main' tracked (was correctly
tracked by build-redbear.sh).

# kernel reports a st_size of 0 even though it is not an empty file) to a
