chore: Upgrade httpx to ^0.28.0 and respx to ^0.22.0 for Python 3.8+

[ojxio]

This PR completes the httpx bump to version ^0.28.0 by updating the lock file, which was missing from a previous attempt by #320 .

Changes

• Bump httpx version: ^0.27.0 → ^0.28.0 in pyproject.toml
• Bump respx version: ^0.21.1 → ^0.22.0
• Update poetry lock file to reflect the version change

Context

A previous PR (#320 ) updated the version constraint but didn't regenerate the lock file, which caused CI failures in practice. This PR addresses that by running the lock file update.

Summary by CodeRabbit

• Chores
  • Tightened HTTP client dependency constraints to handle Python 3.8 separately, improving compatibility and reducing installation/runtime issues.
  • Split a development/test dependency into Python-version-specific releases so tooling selects the appropriate release per Python runtime, keeping tests and dev tools current and compatible.

Walkthrough

Updated pyproject.toml: adjusted httpx entries by changing the Python selector on the older entry from <=3.7 → <3.8 and bumping the ^3.8 entry from ^0.27.0 → ^0.28.0; replaced the single respx dev entry with per-Python-version entries (^0.21.1 for <3.8, ^0.22.0 for ^3.8).

Changes

Cohort / File(s)	Summary
Dependency manifest pyproject.toml	httpx entries: { version = "^0.24.0", python = "<=3.7" } → { version = "^0.24.0", python = "<3.8" } and { version = "^0.27.0", python = "^3.8" } → { version = "^0.28.0", python = "^3.8" }. respx dev dependency: respx = "^0.21.1" → multi-entry list: { version = "^0.21.1", python = "<3.8" } and { version = "^0.22.0", python = "^3.8" }.

Poem

🐰 I nibbled toml lines, nudged versions with glee,
httpx hopped up and respx split by Python degree.
A tidy little change, sorted by version and day —
I thumped a carrot, then bounded away. 🥕

The raw_summary confirms that httpx was upgraded from ^0.27.0 to ^0.28.0 for Python 3.8+ and that respx was updated from a single version to a matrix with ^0.22.0 for Python 3.8+, matching what the title states. The title is concise, specific, and avoids vague terminology or noise, making it immediately clear to teammates reviewing history what the main changes are.

Resolved the httpx upgrade compatibility issues:

• The tests were failing because respx version 0.21.1 was not compatible with httpx 0.28.0 that was recently upgraded in the project.
• Upgraded respx from version 0.21.1 to 0.22.0.

31-34: Respx matrix is logically correct; minor formatting inconsistency.

The respx version matrix (^0.21.1 for Python ≤3.7, ^0.22.0 for Python ^3.8) properly aligns with the httpx 0.28.0 compatibility requirement mentioned in the PR.

However, there's a minor formatting inconsistency: the respx entries use {version = ... while the httpx matrix above uses { version = ... (note the space after the opening brace).

Apply this diff to align spacing with the httpx matrix:

 respx = [
-    {version =  "^0.21.1", python = "<=3.7" },
-    {version =  "^0.22.0", python = "^3.8" },
+    { version = "^0.21.1", python = "<=3.7" },
+    { version = "^0.22.0", python = "^3.8" },

13-16: httpx version matrix update looks good.

The constraint maintains backward compatibility for Python 3.7 (keeping ^0.24.0) while bumping to ^0.28.0 for Python 3.8+, aligning with the respx compatibility requirements noted in the PR. The matrix structure is consistent with how other conditional dependencies are specified.

Hi @chyroc , sorry about that, I was just able to have a python3.7 environment to run the unit tests. Now I fixed this, please take another look~
