* abstract making suggestions out from GithubApiClient
* support more true-ish values for summary-only env var
* merge similar review comments and add test
* switch to cspell pre-commit hook and update other pre-commit hooks

also fix some errors:
1. about filter files per clang tool
2. merged suggestions' file name must match exactly
3. tool summary exclusion from PR review summary
   when tool was not used at all OR review was not requested from a particular tool

- fixes libgit2 diff parsing errors in paginated responses about changed files' diff.
- allows renamed files to be scanned entirely when the source file's content has not changed (when using paginated responses)
- add tests, but ignores coverage for critical errors (like malformed JSON responses)

With the html marker used in our other generated comments. This is to avoid ambiguity and help on-board new features in #131.

Born from the discussion in #129 and continued in #130. This adds timeout-oriented functions for reading and writing to the scanned source files.

This supersedes #130 and resolves #129.
