HAP/MAP packaging removal in holoscan-cli v4.3 — deprecation notice

[wyli]

The upcoming holoscan-cli v4.3 release intentionally drops the Holoscan Application Package (HAP) / MONAI Application Package (MAP) application packaging workflow that previous releases exposed via:

• holoscan package
• holoscan run (HAP)
• holoscan nics
• the monai-deploy console script

The CLI is being consolidated around the HoloHub-style source-project lifecycle (build / run / test / install / lint / container / info commands). HAP / MAP container packaging is out of scope for that surface and the implementation is being removed rather than carried forward.

What this means

• Anyone running those commands from a current install will continue to work until v4.3 ships.
• In v4.2, typing any of those names prints a removal note pointing back at this issue and exits 2.

Workarounds

• Pin holoscan-cli<=4.2.0 — the last release that shipped the HAP / MAP interface.
• Or use the Holoscan SDK packaging workflows directly (see the Holoscan SDK User Guide).
