Fix dependency resolution for dev installs

[akshatvishu]

Problem

Installing dev dependencies fails due to incompatible dependency constraints.

Snowflake connector conflict

• snowflake-ml-python>=1.21.0 requires snowflake-connector-python>=3.17.3,<4
• cortex pinned snowflake-connector-python==3.12.3
  Which results in [dev] and [all] extras being unsatisfiable

uv sync --extra dev
  × No solution found when resolving dependencies for split (markers: python_full_version >= '3.12' and sys_platform == 'linux'):
  ╰─▶ Because snowflake-ml-python>=1.21.0 depends on snowflake-connector-python[pandas]>=3.17.3,<4 and only the following versions of snowflake-ml-python are available:
          snowflake-ml-python<=1.21.0
          snowflake-ml-python==1.22.0
      we can conclude that snowflake-ml-python>=1.21.0 depends on snowflake-connector-python>=3.17.3,<4.
      And because arctic-training[all] depends on snowflake-connector-python==3.12.3, we can conclude that arctic-training[all] and snowflake-ml-python>=1.21.0 are incompatible.
      And because arctic-training[all] depends on snowflake-ml-python>=1.21.0 and your project requires arctic-training[all], we can conclude that your project's requirements are
      unsatisfiable.

Python version / Sphinx conflict

• requires-python = ">=3.8" includes Python versions no longer supported by current sphinx
• sphinx>=8.1.3 requires Python >=3.10
  This results in dependency resolution fails even when using Python 3.10+

uv sync --extra dev
  × No solution found when resolving dependencies for split (markers: python_full_version == '3.9.*' and sys_platform == 'linux'):
  ╰─▶ Because the requested Python version (>=3.8) does not satisfy Python>=3.10.0 and sphinx==9.1.0 depends on Python>=3.12, we can conclude that sphinx==9.1.0 cannot be used. (1)

      Because the requested Python version (>=3.8) does not satisfy Python>=3.10.0 and sphinx==8.1.3 depends on Python>=3.10, we can conclude that sphinx==8.1.3 cannot be used.
      And because we know from (1) that sphinx==9.1.0 cannot be used, we can conclude that all of:
          sphinx==8.1.3
          sphinx>=9.1.0
       cannot be used.
      And because sphinx==8.3.0 was yanked (reason: Bad release), we can conclude that all of:
          sphinx==8.1.3
          sphinx==8.3.0
          sphinx>=9.1.0
       cannot be used. (2)

      Because the requested Python version (>=3.8) does not satisfy Python>=3.10.0 and all of:
          sphinx>=8.2.0,<=8.2.3
          sphinx>=9.0.0,<=9.0.4
      depend on Python>=3.11, we can conclude that all of:
          sphinx>=8.2.0,<=8.2.3
          sphinx>=9.0.0,<=9.0.4
       cannot be used.
      And because we know from (2) that all of:
          sphinx==8.1.3
          sphinx==8.3.0
          sphinx>=9.1.0
       cannot be used, we can conclude that sphinx>=8.1.3 cannot be used.
      And because only the following versions of sphinx are available:
          sphinx<=8.1.3
          sphinx==8.2.0
          sphinx==8.2.1
          sphinx==8.2.2
          sphinx==8.2.3
          sphinx==8.3.0
          sphinx==9.0.0
          sphinx==9.0.1
          sphinx==9.0.2
          sphinx==9.0.3
          sphinx==9.0.4
          sphinx==9.1.0
      we can conclude that sphinx>=8.1.3 cannot be used.
      And because arctic-training[all] depends on sphinx>=8.1.3 and your project requires arctic-training[all], we can conclude that your project's requirements are unsatisfiable.

      hint: The `requires-python` value (>=3.8) includes Python versions that are not supported by your dependencies (e.g., sphinx==9.1.0 only supports >=3.12). Consider using a more
      restrictive `requires-python` value (like >=3.12).

      hint: Pre-releases are available for `sphinx` in the requested range (e.g., 9.1.0rc2), but pre-releases weren't enabled (try: `--prerelease=allow`)

      hint: While the active Python version is 3.12, the resolution failed for other Python versions supported by your project. Consider limiting your project's supported Python versions
      using `requires-python`.

Reproduction

uv sync --python 3.12 --extra dev

Solution

classifiers = [
   "Programming Language :: Python :: 3.12",
 ]
-requires-python = ">= 3.8"
+requires-python = ">=3.10"


 [project.optional-dependencies]

 cortex = [
-    "snowflake-connector-python==3.12.3",
+    "snowflake-connector-python>=3.17.3,<4",
 ]

@sfc-gh-dhung @sfc-gh-mwyatt Apologies for the direct ping but I wanted to flag that the snowflake-ml-python>=1.21.0 dependency introduced in #330 is the root cause of the resolution failure described above.
Could you take a look when you have a moment?

Thank you for the contribution!

@sfc-gh-caxu does Arctic Synth need any particular version of snowflake-connector-python, or can we remove version constraints for it altogether? (Or just something broad like >=3.12.0)?
