Pushed 0d94356 to fix the source-policy failure. All 11 migrated crates now inherit the workspace's thiserror 2 dependency, and their obsolete thiserror 1 exceptions were removed. The Dependabot lockfile is unchanged; no policy bypass or replacement exception was added.

Local validation passed: tests for all 11 affected crates on Linux, readiness script tests, source policy against base 4232f48, release-age policy, formatting, and CLI version consistency. Native Windows behavior was not tested locally. Existing CI had passed Clippy, Test, TUI, audit, and coverage before this inheritance-only correction; fresh CI must pass before merge. No merge performed.

@dependabot rebase

[dependabot]

Looks like this PR has been edited by someone other than Dependabot. That means Dependabot can't rebase it - sorry!

If you're happy for Dependabot to recreate it from scratch, overwriting any edits, you can request @dependabot recreate.

[echobt]

Superseded by #36, recreated from current main on deps/thiserror-2.0.20 because this edited Dependabot branch can no longer rebase automatically. The replacement migrates the eleven remaining direct 1.x consumers to workspace thiserror 2.0.20, removes their obsolete compatibility exceptions, and preserves unrelated locked packages. No release or tag is being created.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
