Deps: nerves_discovery 0.1.4 + toolchains 15.3.1

[bbangert]

Summary

Patch-level dependency freshness bump. mix.lock only — mix.exs
constraints already admit both new versions (no mix.exs edit needed).

nerves_discovery 0.1.3 -> 0.1.4

• diff.hex.pm: https://diff.hex.pm/diff/nerves_discovery/0.1.3..0.1.4

Changelog (CHANGELOG.md v0.1.4):

* Fixes
  * Fix wait calculation on macOS. Previously waits <1 second would result in
    timeout of 0 which was infinite.

Code diff — lib/nerves_discovery/macos.ex:

-    timeout_secs = min(div(timeout, 1000), 1)
+    timeout_secs = max(div(timeout, 1000), 1)

min(..., 1) clamped every timeout to at most 1s and, for any sub-second
timeout, produced 0 — which macOS timeout(1) treats as "no limit"
(infinite wait). max(..., 1) floors it to 1s instead. Scoped to
NervesDiscovery.MacOS.discover_service/2 (macOS-only dev-host mix discover tooling) — no effect on device runtime or non-macOS hosts.
Low risk.

nerves_toolchain_{aarch64,armv6,armv7,riscv64}_nerves_linux_gnu 15.3.0 -> 15.3.1

• https://diff.hex.pm/diff/nerves_toolchain_aarch64_nerves_linux_gnu/15.3.0..15.3.1
• https://diff.hex.pm/diff/nerves_toolchain_armv6_nerves_linux_gnueabihf/15.3.0..15.3.1
• https://diff.hex.pm/diff/nerves_toolchain_armv7_nerves_linux_gnueabihf/15.3.0..15.3.1
• https://diff.hex.pm/diff/nerves_toolchain_riscv64_nerves_linux_gnu/15.3.0..15.3.1

No meaningful Hex-package code/binary diff (prebuilt GCC toolchain
wrappers). Upstream release notes
(gh api repos/nerves-project/toolchains/releases/tags/v15.3.1):

This release only affects toolchain metadata. It has the same GCC
versions as v15.3.0.

• Changes
  • Allow Nerves 2 to be used
  • Remove old unused Elixir code that created compile-time dependencies
    with Nerves tooling.

Confirmed in the lock diff: each toolchain's embedded {:nerves, ...}
requirement widened from "~> 1.13" to "~> 1.13 or ~> 2.0-dev",
consistent with "Allow Nerves 2 to be used." No GCC version change. Low
risk — metadata-only republish.

Lock diff

Exactly five rows moved in mix.lock (verified via git diff mix.lock,
no stray rows, no deps.unlock --all used):

nerves_discovery 0.1.3 -> 0.1.4
nerves_toolchain_aarch64_nerves_linux_gnu 15.3.0 -> 15.3.1
nerves_toolchain_armv6_nerves_linux_gnueabihf 15.3.0 -> 15.3.1
nerves_toolchain_armv7_nerves_linux_gnueabihf 15.3.0 -> 15.3.1
nerves_toolchain_riscv64_nerves_linux_gnu 15.3.0 -> 15.3.1

Verification

• MIX_TARGET=host mix compile --warnings-as-errors — pass (exit 0)
• mise run test (full suite) — 1607 passed (2 doctests, 1605 tests), 3 excluded, 0 failures
• MIX_TARGET=host MIX_ENV=dev mix dialyzer — pass ("done (passed successfully)", 7 known pre-existing errors skipped via .dialyzer_ignore.exs)

Not merging — for review.
