TestPion 0.48.1

Fixes for 0.48.0, found by the macOS, Linux and Windows test runs.

Fixes

• Where an AI proposal may write is decided the same way on every OS: a target path (--path of testpion ai run and testpion flow generate, an RPC's or MCP tool's path, a hand-edited proposal, an undo record, and the MCP tool write_test_file) must be a /-separated path inside tests/ ending in .yaml, .yml or .json. A Windows path (C:\…, C:/…, \\server\share), a backslash (..\x.yaml), .., a leading /, percent-encoding, control characters, empty folder names, names Windows cannot hold (CON, a:b, a trailing dot) and over-long paths are refused before anything is sent — on Linux and macOS a path like C:\Windows\x.yaml used to be accepted as a file name inside tests/. Writing also checks where the file really lands, so a link inside tests/ that leads elsewhere is refused.
• Runs always end, and are recorded when they do: a collection run with bail (testpion run-collection --bail) stopped at the first failure but then never finished; it now ends there with its results recorded. A run whose results file cannot be written (a full disk, a folder in the way) now fails with that reason instead of waiting forever (and no longer raises an unhandled error).
• Cancelling a data-driven flow run never starts another row: a row being read from the data at the moment of the cancel (or of a bail by another row) no longer starts, and is no longer counted as a cancelled row; only the rows that were running are.
