Companion to GenericJam/mob#220 and the matching mob_dev PR.

Generated .tool-versions / priv/zig-version pin 0.17.0. iOS build.zig / build_device.zig templates glob $mob_dir/ios/*.swift with std.Io.Dir.openDirAbsolute because Zig 0.17.0 removed Build.build_root.

Verified: generator lockstep tests and the iOS glob tests (sim + device). zig build --help configure of the rendered templates succeeds on 0.17.0; the old b.build_root.handle.openDir form fails configure.

Not verified: full iOS binary link / device deploy.

New apps get this automatically. Existing apps need Zig 0.17.0 plus a port (or regenerate) of the two iOS build files.

Maintainer update. I rebased this onto current master and added commits on top; thanks @youfun.

Added on top of the original change

• Rebased over the OTP 29.1.2 release; .tool-versions keeps erlang 29.1.2.
• Further 0.17.0 API fixes: std.mem.printSentinel (the stdlib marks bufPrintSentinel deprecated) and dupeSentinel in place of the removed dupeZ in mob_stored_queue.zig.
• iOS templates: the Swift glob now calls b.dependOnDirectoryContents on mob/ios. Zig 0.17.0 caches the configure step, so without that a Swift file mob adds is missed until the Zig cache is cleared. I reproduced this; a regression test now builds twice with one cache.
• mob.doctor: fails a glob that still uses b.build_root and warns when the glob is not tracked. It ignores comments and strings.
• CI runs the pinned Zig, read from .tool-versions or priv/zig-version:
  • mob compiles mob_nif.zig for Android and runs every Android Zig test.
  • mob_dev has a macOS job for :requires_zig.
  • mob_new has a macOS job for the generated build.zig link tests.
• CHANGELOG upgrade steps: mise use zig@0.17.0 in each app, and the iOS glob block.

Checked on real devices with Zig 0.17.0, using an app generated from the three branches. mix mob.deploy --native worked on all three: the Moto G (Android arm64) and the iPhone 17 simulator booted and rendered the home screen, and the physical iPhone SE built and launched.

Review

• Codex rounds 1–3: DO NOT SHIP. Every finding is fixed.
• Round 4 went to a reviewer subagent, because Codex was usage-limited: SHIP. Its nitpicks are fixed.
