Update the CONTRIBUTING.md to build quality in the recent PRs

AI has been used to grammar check the change and sentence restructing whereever required, and review em dashes. I've read through the suggested change and updated whereever required

[Copilot]

Pull request overview

Updates CONTRIBUTING.md with additional contributor and maintainer guidance aimed at reducing low-effort / spammy issues and PRs, including explicit expectations for AI-assisted submissions and clearer issue-triage norms.

Changes:

• Adds new guidance sections covering AI-assisted contributions, PR etiquette, issue assignment expectations, issue quality requirements, and how to report spam/abuse/security issues.
• Expands “Finding Issues” guidance to require a short, contributor-written plan (and discourages AI-generated “claim” comments).
• Cleans up a few formatting/details in the commit message guidelines examples and rules table.

• The PR description says "no-em dashes", but this newly added text introduces an em dash (—). Either update the PR description to reflect current formatting intent, or adjust the new text to avoid em dashes for consistency with the stated goal.

Found something you'd like to work on? Excellent! Just leave a comment like
"I'd like to work on this" — that's all it takes to claim it.

• This implies that a simple “I’d like to work on this” comment is enough to claim an issue, but the new “Issue Assignment” section later explicitly says contributors should include an intended approach and that issues won’t be formally assigned until there’s a draft PR. This is internally inconsistent guidance and will confuse new contributors.

• In the label list, add a comma before “or other label” for correct punctuation; as written, it reads like kind/security or other is a single label.

For new features or larger work, assign the issue to the developer if
known, or add a `kind/release`, `kind/packages`, `kind/security` or other label
once the owning group is absolutely clear, and link it to the relevant milestone.

• Spelling is inconsistent with the rest of the repository’s docs: elsewhere the project uses “behavior” (e.g., RELEASES.md), but this new section uses “behaviour”.

- Expected vs. actual behaviour

CONTRIBUTING.md:39

• The new Table of Contents entries (AI-Assisted Contributions, Pull Request Etiquette, etc.) are indented as siblings of “Authoring PRs”, but their corresponding headings are ### sections inside the “Authoring PRs” section. This breaks the TOC hierarchy and makes these entries appear as top-level Development items rather than sub-items of Authoring PRs.

    - [AI-Assisted Contributions](#ai-assisted-contributions)
    - [Pull Request Etiquette](#pull-request-etiquette)
    - [Issue Assignment](#issue-assignment)
    - [Issue Quality Bar](#issue-quality-bar)
    - [Coordinated or Bulk-Filed Issues and PRs](#coordinated-or-bulk-filed-issues-and-prs)

I think we need to specify what "a while" means

[dongsupark]

What "a while" means comes right below in the text. say 2-3 weeks, but contributors are advised to use their own judgment. :-)

• The table of contents links to a non-existent #reporting-spam-or-abuse section. The closest matching section below is titled Low-Quality Activity Is Discouraged, so the TOC entry currently becomes a broken link.

### Low-Quality Activity Is Discouraged

Looks like a good start.
