Pranay Prakash 918a2c558c docs: replace migration guides with a Comparisons section (#2676)
* docs: replace migration guides with a Comparisons section

Add a Comparisons section (v4 + v5) with an index/snapshot across all frameworks and deep-dive pages for Temporal, Cloudflare Workflows, AWS Step Functions, AWS Bedrock AgentCore, Inngest, and trigger.dev. Remove the old migration-guides section, folding its concept-mapping and migration content into the relevant comparison pages, and repoint top-level nav in both versions.

* docs: refresh comparison pages with current facts (July 2026)

Re-verified each comparison against the vendor's current public docs and
updated what changed since the June 2026 snapshot:

- Temporal: Worker Versioning is now GA; Serverless Workers (AWS Lambda,
  pre-release) scale to zero, so soften the blanket "no scale-to-zero";
  drop the unsubstantiated "Uber" customer claim (Uber is Cadence's origin,
  not a Temporal customer).
- Cloudflare Workflows: note the new per-step billing dimension (500K/mo
  included, then $0.80/100K) landing no earlier than Aug 10, 2026; note the
  50K concurrency ceiling was raised from 4,500 at GA.
- AWS Bedrock AgentCore: add newer GA modules (Harness, Policy, Evaluations);
  correct compliance (SOC/PCI/ISO under internal assessment, audits pending;
  FedRAMP not yet authorized; drop GovCloud claim); refresh languages
  (@aws/agentcore CLI scaffolds TS or Python); "some modules preview" is stale.
- Inngest: Pro pricing $75 -> $99/mo; encryption middleware now TS + Python;
  AgentKit/Realtime are Developer Preview and Connect is public beta; self-host
  is community/best-effort (not "unsupported"); Free-tier run duration 30 days
  vs 366 on Pro; soften funding to ~$30M+.
- AWS Step Functions & trigger.dev: facts re-confirmed; date stamp only.

Bumped every "as of June 2026" stamp to July 2026. v4 and v5 kept identical.

* docs: present comparisons in the present tense; v5-only; Pro usage-based pricing

Follow-up pass on the comparison pages:

- Remove all date references (past and future). Anything that lands on a
  date is stated as already in effect: Cloudflare's per-step billing, Temporal
  Serverless Workers and GA Worker Versioning, AgentCore's Harness/Policy/
  Evaluations modules. Dropped "as of July 2026" stamps, founding/GA years,
  funding round dates, and roadmap/"being added" phrasing.
- Workflow SDK: reference v5 only and treat it as GA (was "v4 GA / v5 beta").
- Pricing and limits: quote the Pro/paid tier only and usage-based rates only;
  drop plan-included quotas and free-tier allowances (Step Functions 4K/mo free,
  Cloudflare 500K steps/mo included, Inngest 50K free execs, Inngest/Free 30-day
  run cap, Temporal $100/mo plan minimum).

v4 and v5 kept identical.

* docs: tighten comparison maturity/status wording

- Drop dateless "upcoming change" phrasing: AgentCore compliance now states
  current facts only (no "self-assessed"/audit-pending implication); remove
  Inngest's "SSPL → Apache after 3 yrs" license-conversion note.
- Don't label the Workflow SDK "GA" — non-beta is the default; also drop bare
  "GA" where it only meant "not beta" (Temporal "7 SDKs", Inngest "TypeScript",
  competitor maturity cells).
- Maturity cells no longer cite version numbers; they describe backing/track
  record instead (e.g. "Built and maintained by Vercel", "Backed by AWS").

v4 and v5 kept identical.

* docs: make "features without a 1:1 equivalent" sections directional

Rename each heading to name the competitor that has the feature (e.g.
"Temporal features without a direct Workflow SDK equivalent") and add a
lead-in clarifying these are the competitor's capabilities the Workflow SDK
doesn't replicate one-to-one, with how to cover each on the Workflow SDK side.

v4 and v5 kept identical.

* docs: point world links at the /worlds routes

The comparison pages linked to /docs/deploying/world/* and
/docs/deploying/building-a-world, which no longer exist in the docs
trees (the Docs Links check rejects them on v5 pages, where /docs hrefs
are render-rewritten and skip the legacy redirects). Link the canonical
/worlds/* routes directly, in both body links and frontmatter refs.

v4 and v5 kept identical.

* docs: address toolbar review feedback on the comparison pages

- Drop the Maturity row from every at-a-glance table
- Add a "what the limits mean in practice" paragraph to each comparison,
  spelling out what the competitor's caps mean for long-running AI
  workloads, and link Vercel World limits to the pricing doc
- Security cells: lead with zero-config per-run E2E encryption and note
  platform security is per-World, instead of the VM-sandbox framing
- Temporal: drop the throughput sentence and the still-in-preview
  Serverless Workers mention from the performance cell
- Cloudflare: end the recommendation on "already all-in on Cloudflare"
- Convert the "features without a direct equivalent" bullet lists into
  two-column tables so it's unambiguous which product owns each feature
- Fix the Inngest page's "no step cap" cell (Vercel World caps runs at
  10K steps per the pricing doc)

v4 and v5 kept identical.
