fix(install): prune old version bundles instead of piling them up (#1074) (#1075)

Browse Source 
install.sh kept each release in its own versions/<v> dir (~50 MB with the
vendored Node runtime) and only moved the `current` symlink, so old versions
accumulated forever across upgrades. Keep only the just-installed version and
delete the rest; `codegraph upgrade` re-runs install.sh, so this covers
upgrades too. The npm-shim self-heal cache (~/.codegraph/bundles/) prunes the
same way. Windows installs overwrite a single dir in place and were never
affected.

Validated real-world on macOS, Linux (Docker/dash), and Windows (VM): a
v1.1.2 -> v1.1.4 install leaves only the latest behind.

# 5. PATH sanity. Two ways this install can fail to be the codegraph that runs:
# 5. Prune older bundles so they don't pile up across upgrades (issue #1074).
# Each release lives in its own versions/<v> dir (~50 MB with the vendored Node
# runtime). `codegraph upgrade` re-runs this script, which drops in a new dir
# and re-points `current` + the launcher — but it never removed the old dirs, so
# they accumulated indefinitely. Keep only what we just installed ($dest) and
# delete the rest. Safe even if a daemon is still executing an older bundle: on
# POSIX the inode stays alive until that process exits, so removing the dir can't
# break a running process. (Windows installs overwrite a single dir in place and
# never reach this.) The markers below let a unit test run this exact block.

# 6. PATH sanity. Two ways this install can fail to be the codegraph that runs:
# 1. $BIN_DIR isn't on PATH at all.
# 2. A *different* codegraph sits earlier on PATH and shadows ours — most
# often a stale `npm i -g @colbymchenry/codegraph`, whose launcher keeps
