* Addressing issue AcademySoftwareFoundation#1915, remove [0, 1] clamping from ICC profiles.

Currently the clamping is removed ONLY when the the type 0 (simple gamma) TRC is used. In this case the the mirroring around origin is used for the negative values.

Other parametric curves are currently implemented as 1DLuts thus will not handle out of bound values properly. In a later wave we can either convert LUTs to half-domain ones or try to implement them with more complex ops (such as exponent with linear).

* - Fixing the op tests in the inverse direction
- More detailed explanation for the clamp removal in pure-gamma TRC cases.

… in OpenColorIO::ThrowInvalidRegex (AcademySoftwareFoundation#2231)

This turned out to be not a UAF issue but an out-of-bounds-access issue where the throw was accessing the incorrect (and potentially shorter) string with an index derived from another (and potentially longer) string.

…ySoftwareFoundation#2230)

Add dependabot.yml to enable automated dependency updates for:
- GitHub Actions workflows (weekly)
- Python pip packages (weekly)

This follows OpenSSF Best Practices Badge recommendations and
is part of the Step Security hardening measures.

Part of AcademySoftwareFoundation#2035

…n#2229)

This adds a GitHub Actions workflow that signs release artifacts
using Sigstore, following the OpenSSF Best Practices Badge
recommendations. The workflow is triggered on release publication
and:

1. Creates a .tar.gz archive of the source tree
2. Signs the archive using sigstore/gh-action-sigstore-python
3. Uploads both the tarball and .sigstore.json credential bundle

Based on the OpenEXR release-sign.yml workflow template.

Closes AcademySoftwareFoundation#2034

Compared the PR branch head with the main branch head, the only two differences are in the root CMake file: version (2.5.0 vs. 2.5.1) and release type ("dev" vs. "")

All as expected.
