Fix ~219 spelling mistakes in documentation and source code comments

[mr-raj12]

Fixes #4719

Summary

• Fix ~219 spelling errors across 93 files in documentation (.rst, .md),
  source code comments/docstrings, CI scripts, and corresponding test fixtures
• No code logic changes — only human-readable text
• Identified using codespell v2.4.1 with project-specific ignore list, followed by manual review

Examples

Original	Corrected
compabitility	compatibility
environement	environment
maintainence	maintenance
comparision	comparison
mispelled	misspelled
boostrapping	bootstrapping
cheksums	checksums
ambigious	ambiguous

Intentionally preserved

• exmaple.com in finder_data.py (junk filter data, not a typo)
• All variable names, function names, URLs, file paths, regex patterns
• All license rule files, test data, third-party code

Test fixtures updated

• tests/packagedcode/data/plugin/help.txt
• tests/packagedcode/data/plugin/plugins_list_linux.txt
• tests/summarycode/data/todo/todo_present/README.multi-orig-tarball-package-expected-diag.json

Note: Small overlap with #4712 on compabitility in README.rst.

Thanks for this, can this be automated and added to the CI in some way?

Yes, we can integrate codespell in CI.
We can add a lightweight GitHub Actions workflow for this. I can raise an issue and take it up, let me know whether you’d prefer it to run on every PR or as a scheduled (maybe weekly) check, and you can assign it to me.
