fix(docs): add sphinxcontrib-jquery to fix search on Sphinx 7+

[realsudarshan]

What does this PR do?

Fixes the search bar being stuck on "Searching..." on docs.activitywatch.net

Root cause

Sphinx 6+ removed jQuery from its default bundle, but sphinx_rtd_theme
depends on it for search functionality. This caused search to silently
fail and hang indefinitely.

Fix

• Added sphinxcontrib-jquery to dependencies in pyproject.toml
• Added sphinxcontrib.jquery to the extensions list in src/conf.py

Testing

Tested locally by serving the built docs with python -m http.server
and confirmed search returns results correctly after the fix.

Fixes #170

Greptile Summary

This PR fixes the docs search bar hanging on "Searching…" by adding sphinxcontrib-jquery as an explicit dependency and Sphinx extension, restoring the jQuery that sphinx_rtd_theme needs but that Sphinx 7 no longer bundles. The fix is correct and minimal.

Confidence Score: 5/5

Safe to merge — targeted, well-understood fix with no functional regressions.

The change is minimal (one new dependency + one extension entry) and directly addresses a known compatibility gap between Sphinx 7 and sphinx_rtd_theme. No logic is altered, no security surface is affected, and the fix is consistent with the existing codebase style.

No files require special attention.

Important Files Changed

Filename	Overview
pyproject.toml	Added sphinxcontrib-jquery = "*" dependency; version constraint is unconstrained but consistent with other *-pinned deps in the file
src/conf.py	Added sphinxcontrib.jquery to extensions list — correct placement and correct approach for restoring jQuery for sphinx_rtd_theme on Sphinx 7+
poetry.lock	Lock file regenerated with Poetry 2.3.4 (up from 2.1.4); content-hash updated to reflect new pyproject.toml; no other substantive changes
