build: adopt word-to-md-swift 1.0.0 in md-to-word-swift

word-to-md-swift 1.0.0 renamed its module WordToMDSwift → WordToMD (see
CLAUDE.md, Architecture Principles → Module Naming). That is a source-breaking
change, which is why it went to 1.0.0 rather than 0.9.0: three consumers pin
`from: "0.x"`, and SPM reads that as `0.x..<1.0.0`, so a breaking MINOR would
have been picked up automatically by every one of them.

Also widens this package's ooxml-swift range. It was pinned `from: "0.5.1"`,
which resolves to `0.5.1..<1.0.0` — mathematically incompatible with the 3.x
that word-to-md-swift now requires, so resolution failed outright rather than
degrading.

The two test files change only the import line.

Carried along: .gitignore and .claude/settings.json pick up the idd-worktree
isolation path and setting from this session's worktree runs. Unrelated to the
dependency change, listed here so the diff holds no surprises.
