Fix command name inconsistency: align CLI and docs to use xconf

[Copilot]

The binary was named xconf in Cargo.toml, but all CLI help text and documentation referenced rkconf, causing user confusion.

Changes

• CLI command name (src/cli/commands.rs): Updated clap attribute from name = "rkconf" to name = "xconf"
• Documentation: Replaced all rkconf references with xconf across:
  • README.md (15 occurrences)
  • MENUCONFIG_GUIDE.md (1 occurrence)
  • docs/USAGE.md (6 occurrences)
  • docs/API.md (2 occurrences)

All command help text now correctly displays:

$ xconf --help
Usage: xconf <COMMAND>

Commands:
  parse       Parse a Kconfig file and display the AST
  menuconfig  Interactive menu configuration (TUI)
  generate    Generate configuration files
  ...

Original prompt

Problem: Inconsistent command naming

Currently, the binary is named xconf in Cargo.toml, but all documentation and CLI help text refers to rkconf. This creates confusion for users.

Required Changes

1. Update CLI command name in code

File: xtask/xconfig/src/cli/commands.rs

• Line 8: Change #[command(name = "rkconf")] to #[command(name = "xconf")]

2. Update all documentation references

File: xtask/xconfig/README.md

Replace all occurrences of rkconf with xconf:

• Line 90: rkconf saveconfig → xconf saveconfig
• Line 102: rkconf saveconfig → xconf saveconfig
• Line 105-122: All rkconf commands → xconf
• Line 247: rkconf oldconfig → xconf oldconfig
• Line 252: rkconf oldconfig → xconf oldconfig
• Line 256: rkconf generate → xconf generate
• Line 266: rkconf generate → xconf generate
• Line 269: rkconf parse → xconf parse
• Line 279: rkconf parse → xconf parse
• Line 282: rkconf menuconfig → xconf menuconfig
• Line 288: rkconf menuconfig → xconf menuconfig
• Line 300: rkconf defconfig → xconf defconfig

File: xtask/xconfig/MENUCONFIG_GUIDE.md

• Line 68: rkconf menuconfig → xconf menuconfig

File: xtask/xconfig/docs/USAGE.md

Replace all occurrences:

• Line 12: "The rkconf binary" → "The xconf binary"
• Line 18: rkconf parse → xconf parse
• Line 27: rkconf parse → xconf parse
• Line 33: rkconf defconfig → xconf defconfig
• Line 39: rkconf menuconfig → xconf menuconfig
• Line 45: rkconf generate → xconf generate

File: xtask/xconfig/docs/API.md

• Line 366: "The CLI is accessed through the rkconf binary" → "The CLI is accessed through the xconf binary"
• Line 369: rkconf <command> → xconf <command>

File: scripts/make/config.mk

• Line 13: Update help text if it mentions rkconf to use xconf

3. Update installation instructions

Ensure all references in README files mention xconf as the installed command.

Testing

After changes, verify:

cd xtask/xconfig
cargo build --release
./target/release/xconf --help  # Should show "xconf" as the command name

Acceptance Criteria

• All documentation uses xconf consistently
• CLI help text shows xconf as the command name
• No references to rkconf remain in user-facing documentation
• The binary continues to work correctly with the new name
