chore: update cargo-dist, drop self-updater and PR release dry-run

[scarmuega]

What

Bump cargo-dist to 0.30.3 and adjust its config in dist-workspace.toml:

• install-updater = false — stop bundling the axoupdate self-updater in the generated installers.
• pr-run-mode = "skip" — don't run the release dry-run on pull requests. The release workflow (release.yml) now fires only on version tags; PR validation already lives in ci.yml.

.github/workflows/release.yml is regenerated from dist-workspace.toml to match.

Why

• The self-updater isn't wanted for this distribution.
• The dist plan dry-run ran on every PR for no benefit — ci.yml (fmt/clippy/test/check) is the real PR gate.

Verification

• dist generate --check is clean (TOML ↔ YAML in sync).
• dist plan succeeds: all four targets and all installers (shell, powershell, npm, homebrew) present, no updater artifact.
• release.yml on: block now contains only push: tags:.

📝 Walkthrough

Walkthrough

Upgrades cargo-dist from 0.29.0 to 0.30.3 in both dist-workspace.toml and the release workflow installer URL. Removes the pull_request trigger from the release workflow, disables the updater installer, sets pr-run-mode = "skip", and adds a needs.plan.result == 'success' guard on the host job.

Changes

Release pipeline upgrade and hardening

Layer / File(s)	Summary
cargo-dist version bump and PR/updater behavior dist-workspace.toml	cargo-dist-version updated to 0.30.3; install-updater = false added to disable updater installer generation; pr-run-mode = "skip" added to suppress PR dry-run behavior.
Release workflow trigger, installer, and host gate .github/workflows/release.yml	pull_request: trigger removed so the workflow fires only on tag pushes; installer download URL updated to v0.30.3; host job if: condition extended with needs.plan.result == 'success'.

Poem

🐇 Hop, hop, the tags now reign,
No pull requests shall trigger pain.
Version bumped to thirty-three,
The updater's gone — we run free!
Release the carrot, ship the crate! 🥕
