ci: let setup-soldr float soldr binary

[zackees]

Summary

• Remove the explicit version: 0.8.0 input from every setup-soldr workflow step so setup-soldr controls the soldr binary version.
• Move workflow refs from zackees/setup-soldr@v0.9.66 to zackees/setup-soldr@v0; v0 currently points at setup-soldr main, whose action default is soldr 0.8.0 without a repo-local binary pin.
• Change the Windows soldr verification from an exact soldr 0.8.0 assertion to a smoke check that soldr --version returns a soldr version string.
• Update release/template comments so v0.8.0 is described as the known-good floor/history, not the current CI pin.
• Normalize the probe-rs install helper paths to satisfy the existing Dylint ban_std_pathbuf gate that was blocking this PR on current main.

Closes #997

Validation

• gh api repos/zackees/setup-soldr/git/refs/tags/v0 --jq '.object.sha' matches gh api repos/zackees/setup-soldr/commits/main --jq '.sha' (18b1e0f546c53837320e472325ea695bab96f091).
• rg -n -F 'zackees/setup-soldr@v0.9.66' .github ci returned no matches.
• rg -n -F 'version: "0.8.0"' .github ci returned no matches.
• rg -n -F 'test "$version" = "soldr' .github ci returned no matches.
• rg -n 'PathBuf' crates/fbuild-deploy/src/probe_rs.rs returned no matches.
• git diff --check
• uv run --no-project python ci/render_workflows.py --check
• soldr cargo fmt --check

Summary by CodeRabbit

• Bug Fixes
  • Updated CI and release workflows to use the latest setup behavior, reducing reliance on a pinned tool version.
  • Relaxed one Windows validation check so it verifies the tool starts correctly rather than matching an exact version string.
• Documentation
  • Refreshed workflow comments to better reflect the current build and release process.

📝 Walkthrough

Walkthrough

CI workflows across the repository are updated to use the floating zackees/setup-soldr@v0 action instead of the pinned @v0.9.66 with explicit version 0.8.0, with related comment updates and a Windows version-check adjustment. Separately, probe_rs.rs refactors several functions to return NormalizedPath instead of PathBuf.

Changes

Unpin setup-soldr across workflows

Layer / File(s)	Summary
Core CI workflow unpinning .github/workflows/acceptance-205.yml, .github/workflows/bench-205.yml, .github/workflows/check-macos.yml, .github/workflows/check-ubuntu.yml, .github/workflows/docs.yml, .github/workflows/dylint.yml, .github/workflows/fmt.yml, .github/workflows/msrv.yml, .github/workflows/update-data.yml	Switches zackees/setup-soldr from pinned @v0.9.66 with version: "0.8.0" to floating @v0, removing the version input.
Windows workflow unpinning and version verification .github/workflows/check-windows.yml	Unpins setup-soldr to @v0 and changes the verify-soldr check from an exact version match to a soldr prefix check.
Template build workflow unpinning and release comments .github/workflows/template_build.yml, .github/workflows/template_native_build.yml, .github/workflows/release-auto.yml, ci/publish.py	Unpins setup-soldr in template build workflows and updates comments describing macOS/Windows lane restoration and soldr-clang-shim release rationale.

probe_rs.rs NormalizedPath refactor

Layer / File(s)	Summary
Switch probe_rs helpers to NormalizedPath crates/fbuild-deploy/src/probe_rs.rs	Updates imports, staging directory helper, extraction/install function, and file-search helper to use and return NormalizedPath instead of PathBuf/Option<PathBuf>.

🚥 Pre-merge checks | ✅ 4 | ❌ 1

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Out of Scope Changes check	⚠️ Warning	crates/fbuild-deploy/src/probe_rs.rs adds an unrelated path-handling refactor that is outside the setup-soldr CI scope.	Split the probe-rs path-handling refactor into a separate PR so this change stays focused on setup-soldr version pinning.

✅ Passed checks (4 passed)

Check name	Status	Explanation
Linked Issues check	✅ Passed	The PR removes explicit soldr pinning and updates the Windows check to a version-smoke test, matching #997.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly matches the main CI change: letting setup-soldr control the soldr binary version instead of pinning it locally.
