Colin Walters 21babe7616 xtask: Add local-rust-deps command for auto-detecting path dependencies 
Add `cargo xtask local-rust-deps` which uses `cargo metadata` to find
local path dependencies outside the workspace (e.g., from [patch] sections)
and outputs podman bind mount arguments.

This enables a cleaner workflow for local development against modified
dependencies like composefs-rs:

1. Add a [patch] section to Cargo.toml with real local paths
2. Run `just build` - the Justfile auto-detects and bind-mounts them

Benefits over the previous BOOTC_extra_src approach:
- No manual env var needed
- Paths work for both local `cargo build` and container builds
- No /run/extra-src indirection or Cargo.toml path munging required
- Auto-detection means it Just Works™

The Justfile's build target now calls `cargo xtask local-rust-deps` to
get bind mount args, falling back gracefully if there are no external deps.
The old BOOTC_extra_src mechanism is still supported for backwards compat.
