b63aa9dc39 fix(cli): copy and sign the built binary on install instead of re-signing the stale target (#473)
* fix(cli): copy and sign the built binary on install instead of re-signing the stale target

`install` (especially with --force) only ad-hoc-signed whatever already sat at
~/.local/bin/codebase-memory-mcp and never copied the binary the operator ran
install from. An operator who built from source and ran `install -y --force`
was silently left with the OLD binary at the target — running stale code while
believing they had upgraded (#472).

Install now mirrors `update`: detect the running binary, copy it to the
canonical target (skipping the copy when we already ARE the target, which would
otherwise truncate the running file), make it executable, ad-hoc sign the
TARGET, and point all agent configs at the target. A different pre-existing
binary is only replaced with --force or interactive confirmation; --dry-run
reports the intended swap without touching anything.

The copy+sign also resolves the secondary report: a hand-copied clang build is
linker-signed (flags=0x20002) and gets Killed:9 when spawned by an MCP host —
re-signing ad-hoc (flags=0x2) makes it launchable, which install now does for
the placed binary.

Adds cbm_copy_binary_to_target() (with a same-file guard) plus regression tests
covering the binary swap and the self-copy guard.

Closes #472

* fix(cli): address QA round 1

Extend cli_install_same_file_guard_issue472 with a symlink case: two distinct
path strings resolving to the same inode (which a non-canonical
cbm_detect_self_path vs the hardcoded target can produce) must also be detected
as same-file and skipped, not truncated. POSIX-only (#ifndef _WIN32).

* test(cli): guard install copy exec-bit assertion to POSIX

cli_install_copies_binary_to_target_issue472 asserted the executable bit on the
copied target, but cbm_copy_binary_to_target only chmods on POSIX (the exec bit
is not meaningful on Windows, and MinGW stat() derives it from the file
extension). Wrap the stat/S_IXUSR assertion in #ifndef _WIN32 so test-windows
passes; the content and creation assertions still run on all platforms.
