The clap --version flag now shows the git hash alongside the semver
version (e.g. "lore 0.1.0 (a573d69)") instead of bare "lore 0.1.0".
LORE_VERSION is constructed at compile time in build.rs from
CARGO_PKG_VERSION + the short git hash, and consumed via
env!("LORE_VERSION") in the Cli struct's #[command(version)] attribute.

Shutdown signal improvements:
- Upgrade ShutdownSignal from Relaxed to Release/Acquire ordering.
Relaxed was technically sufficient for a single flag but
Release/Acquire is the textbook correct pattern and ensures
visibility guarantees across threads without relying on x86 TSO.
- Add double Ctrl+C support to all three signal handlers (ingest,
embed, sync). First Ctrl+C sets cooperative flag with user message;
second Ctrl+C force-exits with code 130 (standard SIGINT convention).
CLI hardening:
- LORE_ROBOT env var now checks for truthy values (!empty, !="0",
!="false") instead of mere existence. Setting LORE_ROBOT=0 or
LORE_ROBOT=false no longer activates robot mode.
- Replace unreachable!() in color mode match with defensive warning
and fallback to auto. Clap validates the values but defense in depth
prevents panics if the value_parser is ever changed.
- Replace unreachable!() in completions shell match with proper error
return for unsupported shells.
Exit code collision fix:
- ConfigNotFound was mapped to exit code 2 (error.rs:56) which
collided with handle_clap_error() also using exit code 2 for parse
errors. Agents calling lore --robot could not distinguish "bad
arguments" from "missing config file."
- Restore ConfigNotFound to exit code 20 (its original dedicated code).
- Update robot-docs exit code table: code 2 = "Usage error", code 20 =
"Config not found".
Build script:
- Track .git/refs/heads directory for Cargo rebuild triggers. Ensures
GIT_HASH env var updates when branch refs change, not just HEAD.

Add clap_complete for shell completion generation and libc (unix-only)
for SIGPIPE handling. Create build.rs to embed the git commit hash at
compile time via cargo:rustc-env=GIT_HASH, enabling `lore version` to
display the short hash alongside the version number.
