site: tag pages include finds; find-only tags get pages

Tag pages are now generated from the union of entry and find tags —
1,179 tags that existed only on finds (most tag links on find pages)
previously 404'd. Tagged finds render in a compact secondary "Finds"
list below the entry grid, keeping the editorial tier on top. Find-only
tag pages with fewer than 3 finds are noindexed until they fill out.
Tag feeds stay entries-only; the RSS pill and autodiscovery link only
render where a feed exists. Category pages unchanged (finds have no
category).

 - Find slugs are globally unique although folders are date-bucketed; URLs stay flat at `/find/<slug>/`.

+- Finds are reachable through bundles and through tag pages (a secondary "Finds" list under the entry grid on `/tags/<tag>/`) — an unbundled find is still invisible on the home feed, grids, and category pages.
 - `source` frontmatter must exactly match a `name` in `sources.json`.
 - Amazon links: store canonical `https://www.amazon.com/dp/<ASIN>` with no query params; `src/lib/affiliate.ts` adds the tracking ID, badge, and disclosure at render time.
