fix(cli): accept the ./... package pattern in scan - #72
Conversation
`sqlguard scan ./...` — the form the README quick start, the getting-started guide, the scan page, the intro table and the CI snippet all use — failed with `scan failed: lstat ./...: no such file or directory`. The argument reached filepath.Abs verbatim, so the pattern became a directory that does not exist; packages.Load then failed and the AST fallback tried to walk it. The scan was already recursive on both paths (scanViaPackages loads "./..." relative to the target itself), so `dir/...` selects exactly what `dir` does and trimming the suffix is the whole fix. Pinned by an equivalence test that asserts both spellings produce identical output, and by a nested-file test that proves the pattern still reaches subdirectories. The trim is separator-anchored. A directory really named `weird...` is a legal path, and an unanchored trim would point the scan at a sibling `weird` instead — reporting that tree's findings, or a clean exit, for a directory the user never named.

Accept Windows path separators before scanning.
On Windows, filepath.Join(dir, "...") produces a path ending in \.... The /... check leaves that pattern unchanged. The scanner then treats ... as a literal child directory and fails; the new pattern integration tests also fail on Windows. Recognize either path separator on Windows while preserving the handling of root paths. (go.dev)

The go command rewrites `\` to `/` in relative arguments "as a courtesy to Windows developers" (cmd/go/internal/search), so `.\...` is a spelling Windows users do type — and the `/...`-only anchor left it failing exactly as `./...` used to. The trim is guarded on the OS separator rather than applied unconditionally: on Unix a backslash is an ordinary filename byte, so a directory named `weird\...` there must reach the filesystem intact. Trimming it on both platforms would reintroduce the wrong-directory redirect the anchor was added to prevent, just under a different spelling. trimPatternSuffixSep takes the separator so both platforms are covered by the table from either host. Both failure directions are pinned: an unconditional trim fails the three Unix backslash cases, and dropping the branch fails the five Windows ones.

..., this trim scans its parent instead. For example, sqlguard scan ./queries/... cannot target a literal queries/... directory. If the parent has no findings, the command can exit successfully without examining the requested directory. Check whether the literal path exists before treating it as a pattern, or provide a way to address it.

**Literal directory is skipped** If the final path component is an existing directory named `...`, this trim scans its parent instead. For example, `sqlguard scan ./queries/...` cannot target a literal `queries/...` directory. If the parent has no findings, the command can exit successfully without examining the requested directory. Check whether the literal path exists before treating it as a pattern, or provide a way to address it.
