Implement Rubrics methods for Canvas LMS API

[Copilot]

This PR implements comprehensive support for retrieving rubrics data from the Canvas LMS API, addressing the request in issue #19.

Changes Made

Added four new functions following the established package patterns:

Course-Level Rubrics

• get_rubrics(canvas, course_id, per_page = 100) - Retrieves list of rubrics for a specific course
• get_rubric(canvas, course_id, rubric_id) - Retrieves a single rubric by ID from a course

Account-Level Rubrics

• get_account_rubrics(canvas, account_id, per_page = 100) - Retrieves list of rubrics for a specific account
• get_account_rubric(canvas, account_id, rubric_id) - Retrieves a single rubric by ID from an account

Implementation Details

All functions follow the established vvcanvas package conventions:

• ✅ Proper roxygen2 documentation with @export tags
• ✅ Consistent error handling with informative messages
• ✅ Uses httr::GET for HTTP requests and jsonlite::fromJSON for parsing
• ✅ Follows Canvas API authentication patterns with Bearer tokens
• ✅ Includes pagination support where appropriate (per_page parameter)
• ✅ Comprehensive parameter validation

API Endpoints Covered

These functions implement the following Canvas API endpoints:

• GET /api/v1/courses/:course_id/rubrics
• GET /api/v1/courses/:course_id/rubrics/:id
• GET /api/v1/accounts/:account_id/rubrics
• GET /api/v1/accounts/:account_id/rubrics/:id

Usage Example

# Set up authentication
canvas <- list(
  api_key = "your_api_key_here",
  base_url = "https://your-canvas-instance.com"
)

# Get all rubrics for a course
rubrics <- get_rubrics(canvas, course_id = "12345")

# Get a specific rubric
rubric <- get_rubric(canvas, course_id = "12345", rubric_id = "67890")

# Get all rubrics for an account
account_rubrics <- get_account_rubrics(canvas, account_id = "1")

Files Added

• R/get_rubrics.R - Course rubrics list function
• R/get_rubric.R - Single course rubric function
• R/get_account_rubrics.R - Account rubrics list function
• R/get_account_rubric.R - Single account rubric function

Updated TODO.md to mark the corresponding rubrics endpoints as implemented.

Fixes #19.

Update pkdown too

Updated pkgdown configuration and documentation. Added rubrics functions to NAMESPACE exports, created manual pages (.Rd files), and updated _pkgdown.yml with new rubrics section. The functions are now properly documented and will appear on the pkgdown website. (commit 453d600)

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• cloud.r-project.org
  • Triggering command: /usr/lib/R/bin/exec/R -e install.packages(c('roxygen2',~+~'devtools'),~+~repos='REDACTED') (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

@copilot use the new paginate function see other functions how to use it

Updated both get_rubrics() and get_account_rubrics() functions to use the new paginate() helper function following the same pattern as other list functions in the codebase like get_assignments() and get_course_pages(). The functions now properly handle multiple pages of results using paginate(), lapply(), and dplyr::bind_rows(). (commit 8b0ad8e)
