docs(reputation): anchor reputation bootstrap methodology note

[aboyejirebecca-prog]

Closes #503

Adds a new section to docs/ANCHOR_REPUTATION.md explaining how newly onboarded anchors accrue reputation (bootstrap → live): the insufficient_data cold-start state, how the scorecard surfaces "Collecting Data," and how the composite score accrues once outcomes start flowing in. Cross-references lib/reputation/thresholds.ts, aggregate.ts, bands.ts, and ScorecardCard.

Thanks for opening a clean version of the docs PR! Two things to fix before this can move forward:

1. Linked issue missing — the PR body has Closes # with no issue number. Please fill it in (e.g. Closes #503) so the issue auto-closes on merge.

2. PR title — docs/anchor-reputation-bootstrap-methodology-503-clean doesn't follow Conventional Commits. Please rename it to something like docs(reputation): add anchor reputation bootstrap methodology note.

Once both are updated, this will continue through the review gates. Note that your earlier PR #536 covering the same topic is still open — once this one is ready, please close #536 yourself to avoid duplication.

Hi @aboyejirebecca-prog — this PR only touches a docs file (docs/ANCHOR_REPUTATION.md) with no linked issue. Documentation changes should accompany the implementation PR, not land as a standalone PR. Also the PR body is blank. This PR is advised to be closed.

This PR's template is unfilled — the "Closes #" line has no issue number. Per repo contribution guidelines, every PR must link exactly one issue. Please edit the PR description to reference the issue this closes (e.g. Closes #123) and fill in the Summary/Changes/Testing sections so reviewers can verify scope. Re-requesting review once that's added.

Heads up: #503 was already closed by #536 ("docs: add anchor reputation bootstrap methodology note"), merged to main a while back. Current main's docs/ANCHOR_REPUTATION.md has word-for-word identical content to what this PR adds (same tables, same TODO comment, same section headers) — this PR is now fully redundant. Recommending closure; will confirm with the repo owner.
