release(v0.34.4): bump 4 manifests + ratchet floors

[priceflex]

What

Polyglot version bump across the 4 manifests so a tagged v0.34.4 release reports 0.34.4 at runtime (not the stale 0.34.3), plus a floor-guard ratchet so the version-pin tests are a live tripwire instead of decayed background noise.

File	Before	After
proto/Cargo.toml	0.34.3	0.34.4
ns/mix.exs	0.34.3	0.34.4
relay/mix.exs	0.34.3	0.34.4
gateway/mix.exs	0.34.3	0.34.4
proto/tests/version_pin_test.rs MINIMUM_VERSION	0.32.2	0.34.4
*/test/ztlp_*/release_test.exs floor	0.32.2	0.34.4

Why

Three feature PRs have landed on main since v0.34.3 and operators need compiled artifacts:

• feat(D4): Windows NRPT-based DNS interception for ZTLP zones #82 D4 — Windows NRPT-based DNS interception for ZTLP zones
• feat(D5): browser TLS green-lock — real X.509 chain + machine CA install + on-demand SNI cert minting #83 D5 — Browser TLS green-lock (X.509 chain + machine CA + SNI mint)
• feat(D6): UI Setup Wizard — 5-click post-enrollment setup (no CLI required) #84 D6 — UI Setup Wizard (5-click post-enrollment setup)

Per release-version-pinning skill pitfall 13 (floor decay): every release-bump PR ratchets the floor in the SAME commit. The v0.32.2 floor sat through four releases (v0.34.0/.1/.2/.3); that's exactly the decay pattern documented in the skill. Closing it now.

RED → GREEN

RED — floors ratcheted, manifests still at 0.34.3, ran cargo test --test version_pin_test:

test cargo_pkg_version_is_at_least_minimum_floor ... FAILED
proto/Cargo.toml version 0.34.3 is older than the v0.34.4 strict-routing tag.

GREEN — after bumping manifests:

Component	Tests	Result
proto (Rust)	2 / 2	✅
ns (Elixir)	15 / 15	✅
relay (Elixir)	15 / 15	✅
gateway (Elixir)	15 / 15	✅

Details

• Inline manifest comments updated with the bump history (skill convention).
• Floor message names both versions per skill pitfall 3.

Validation

• Manifest semver shape: parseable in all 4 components
• Runtime-vs-declared: passes (Application.spec/:vsn in Elixir, env!("CARGO_PKG_VERSION") in Rust)
• Floor guard: passes at exactly v0.34.4 (eq case)

Follow-up

After merge:

1. git tag v0.34.4 <merge-commit> and push the tag
2. release.yml workflow fires and publishes Rust binaries (5 targets), Elixir OTP releases (3 components), desktop installers (Tauri NSIS/MSI/AppImage/deb), and eBPF source
3. Run scripts/verify_release_artifact_version.sh priceflex/ztlp v0.34.4 0.34.4 to confirm embedded version strings actually match the tag (skill pitfall 11)

Summary by CodeRabbit

• Chores

  • Bumped application version to 0.34.4 across all platform components (gateway, namespace services, protocol library, and relay services).

• Tests

  • Updated version compatibility validation tests to enforce minimum version requirement of 0.34.4.

📝 Walkthrough

Walkthrough

This PR performs a coordinated version bump from 0.34.3 to 0.34.4 across the ZTLP multi-language project. It updates version declarations in all four manifests (gateway, ns, relay, proto) and ratchets release-floor regression tests to enforce a minimum version of 0.34.4, preventing accidental downgrades.

Changes

Version bump to 0.34.4

Layer / File(s)	Summary
Version declarations in manifests gateway/mix.exs, ns/mix.exs, relay/mix.exs, proto/Cargo.toml	Version field updated from 0.34.3 to 0.34.4 in all Mix and Cargo manifests.
Release-floor regression test updates gateway/test/ztlp_gateway/release_test.exs, ns/test/ztlp_ns/release_test.exs, relay/test/ztlp_relay/release_test.exs, proto/tests/version_pin_test.rs	Version-floor assertions raised from 0.32.2 to 0.34.4 using Version.compare/2 logic; failure messages updated to reference the new minimum tag.

Poem

🐰 Four homes all bumped with glee,
From point-three to point-four, you see—
The version ratchet clicks just so,
Regression tests keep downgrades low!
