Pricing FAQs overhaul for May 14, 2026 changes (#73)

* Overhaul pricing FAQs for May 14, 2026 pricing changes

* Delete the entire 'Warp's pricing change FAQs (Oct 30, 2025)' section
  and remove the stale anchor link from the 'How can I get the most out
  of my Warp plan?' callout.
* Rewrite plan-recommendation copy with qualitative Build / Max /
  Business / Enterprise positioning; replace 'enforced team-wide ZDR'
  language with 'admin-configurable data controls' and split model-
  provider ZDR out as a separate, all-plan concept.
* Update the Lite-model FAQ to mention BYOK and Custom Inference
  Endpoint (CIE) alongside Reload credits.
* Add new FAQs: multi-seat team credits with grandfathered pooled
  credits, what-to-do-when-you-need-more-AI-usage (Max + Reload + BYOK +
  CIE), how auto-reload works for teams, and how service-account /
  team-scoped API key requests are billed on self-serve plans.
* Add BYOK-on-all-plans and CIE FAQs; rename 'Add-on Credits' to
  'Reload credits' and fix one remaining stale anchor link inside the
  downgrade caution callout.
* Add new tail-end 'Warp's pricing change FAQs (May 14, 2026)' section
  covering seat limits + grandfathering, Reload credits attribution
  change, Max plan credit-allocation change + grandfathering, BYOK on
  Free, the CIE launch, and the ZDR / data-controls clarification.

Per the editorial rule, no per-plan monthly credit counts are
hard-coded; the page links to warp.dev/pricing for current allowances.

* Add BYOK / CIE org-size disclosure to pricing FAQs

Per PR #73 follow-up: BYOK and custom inference endpoint support are
available to individual users and organizations with 10 or fewer
employees; larger organizations need a Business or Enterprise plan.

* 'Can I bring my own API key?' FAQ: append the verbatim disclosure
  paragraph at the end of the answer.
* 'Does Warp support custom inference endpoints?' FAQ: same.
* 'What if I need more AI usage than my plan includes?' FAQ: add a
  one-line italicized cross-reference below the BYOK / CIE bullets
  pointing to the BYOK FAQ above.

* Add Custom inference endpoint page stub for CI link check

This file is the canonical version created on PR #71
(hyc/plan-updates-byok-cie). It is duplicated here so that the
link checker on this branch can resolve the relative references
to /support-and-community/plans-and-billing/custom-inference-endpoint/
that this PR introduces.

When PR #71 merges into hyc/plan-updates, git will reconcile the
identical file contents automatically.

* docs(pricing-may-2026): add platform-credits caveats, expand service-account FAQ, new platform-credits FAQ

Adds platform-credits caveats to the BYOK, custom inference endpoint, and "What if I need more AI usage" FAQs so Business/Enterprise readers know local agent runs that use customer-supplied inference still consume platform credits.

Expands the service-account / team-scoped API key FAQ to introduce the task billing principal concept, spell out the owner-pool waterfall, describe auto-reload off vs on behavior, and clarify that attribution stays on the service account while billing rolls up to the team owner. Expands the Enterprise note in that FAQ to cover team-scoped credit pool depletion and the PAYG fallback.

Adds a new "How do platform credits factor in?" FAQ after the multi-seat credits FAQ, summarizing the three credit buckets (AI, compute, platform) and when platform credits apply.

Pre-existing build error (CIE page missing from sidebar topic) is unrelated to this change and is fixed by PR #71's src/sidebar.ts update once it merges into the umbrella.

* Remove duplicate CIE stub; PR #71 owns the canonical custom-inference-endpoint.mdx

The CIE page is owned by PR #71 (hyc/plan-updates-byok-cie), which also
adds the matching src/sidebar.ts entry. Removing the stub here so the
PR #73 \u2192 umbrella merge auto-resolves cleanly after #71 lands.
