Kaoru0822 fc791bb606 fix(paths): select caller paths through symlinks and .. as the filesystem does (#4067)
* fix: select caller paths through symlinks and .. as the filesystem does

CLI adapters, binary target resolution, the reverse-engineering service
and the objdump and Rizin command builders made caller-selected paths
absolute with path.resolve, which collapses `link/..` lexically. On
POSIX the filesystem follows `link` first, so these commands inspected,
hashed or launched a different file and returned internally consistent
Evidence for it.

absoluteCallerPath now owns that step: on POSIX it prefixes a relative
path with the working directory and keeps an absolute path as spelled;
on Windows, where `..` resolves lexically, it keeps win32.resolve.

Fixes #3864
Fixes #3911
Fixes #3912

* fix: keep firmware, WASM list and output-root paths on the selected file

Review follow-up. The CLI already passed firmware and WASM paths through
absoluteCallerPath, but snapshotFirmware and SafeOutputTree.create
re-resolved them lexically, and the WASM glue and candidate lists still
used resolve, so those inputs could still select a sibling file or
create output beside the intended directory.

absoluteCallerPath now also drops `.` segments and repeated or trailing
separators on POSIX, which never change the named file, so selected
paths such as `./module.wasm` keep matching their glue references
exactly. Every `..` is still left for the filesystem.

SafeOutputTree keeps host path syntax; its platform argument selects only
the Windows name policy.

* fix: keep directory requirements and relative cwd in caller paths

Review follow-up. absoluteCallerPath stripped a trailing `/` or `/.`, so
`file/` selected the regular file instead of failing with ENOTDIR; it
now keeps one trailing separator. A relative cwd option was appended to
the root; it is now made absolute without collapsing `..`. WASM glue
matching resolved local literals lexically, so a module selected through
`link/..` matched only by basename; the adapter now compares both sides
through absoluteCallerPath and still reports each candidate as given.
