install.sh: add bun >= 1.2 version check — v6 bun.lock format fails on older system bun with confusing error

[badosanjos]

Summary

The v6.0.0 bun.lock files use the newer lockfile format that requires bun >= 1.2. install.sh checks that some bun exists (and auto-installs latest when absent) but accepts any pre-existing bun. With a system bun 1.1.x present, the bootstrap succeeds and everything appears fine until the Pulse dashboard build, which fails with:

error: Unknown lockfile version
    at bun.lock:2:22
InvalidLockfileVersion: failed to parse lockfile: 'bun.lock'

Suggestion

In install.sh prereqs, check bun --version against a minimum (>=1.2) and offer the same auto-install path used when bun is absent. Cheap check, saves a confusing failure much later in setup.

Environment

Ubuntu 24.04 with system bun 1.1.42; fixed locally by installing current bun per-user.

Thanks — this is implemented in the development source: install.sh now checks bun --version against a minimum of 1.2 and runs the same auto-install path whether bun is absent or too old, so the v6 bun.lock format failure can't surface late in setup anymore. Ships with the next release. Closing as integrated.
