feat(phase0): rename /agent-platform/ → /agents/ (IA restructure Phase 0) - #420

…#14649)

## Summary
warpdotdev/docs#420 (merged 2026-08-03) renamed `/agent-platform/...`
docs URLs as part of the IA restructure Phase 0. 308 redirects keep the
old links working today, but the in-app hardcoded
`docs.warp.dev/agent-platform/...` links in this client (agent tips,
ambient-agent tips, cloud setup guide, AI settings, MCP list page, HOA
onboarding, zero-state block, auth secret types, agent SDK ambient CLI
output, the bug report issue template, and the bundled `oz-platform`
skill) should point at their final canonical paths instead.

This is a mechanical link-hygiene rewrite, not a blind
`/agent-platform/` -> `/agents/` replace:
- Capabilities / local-agents / inference content -> `/agents/...`
- Cloud-agents content -> `/platform/...` (not
`/agents/cloud-agents/...`), per the docs `vercel.json` `:path*` rewrite
plus specific overrides (e.g. `cloud-agents/overview` -> `/platform/`,
`cloud-agents/platform` -> `/platform/overview/`)
- Special alias: `warp-agents/agent-notifications` ->
`agents/capabilities/agent-notifications`
- `.github/ISSUE_TEMPLATE/01_bug_report.yml`'s `ai-faqs` link ->
`agents/getting-started/faqs/`
- Bundled `oz-platform` skill's `computer-use.md` link ->
`agents/capabilities/computer-use.md`

Out of scope (left untouched per the ticket):
`crates/warp_core/src/ui/icons.rs`'s `GeminiEnterpriseAgentPlatform`
icon (an SVG asset path, not a docs URL) and
`.agents/skills/review-pr-local/SKILL.md` (an internal engineering skill
doc, not a shipped in-app/product surface).

### Rework changes
- ⚠️ [IMPORTANT] `https://docs.warp.dev/platform/environments` returned
a 308 redirect to `https://docs.warp.dev/platform/environments/`,
leaving a redirect hop. **Implemented**: added the trailing slash at
both call sites in `app/src/terminal/view/ambient_agent/tips.rs` (lines
85 and 141), and re-verified with a no-follow `curl` request that it now
returns a direct 200.
- Additional instruction to re-check every docs URL touched by this PR
with a no-follow request: **Implemented**. Re-extracted all 31 unique
docs.warp.dev URLs added by this PR's diff and checked each with `curl
-sS -o /dev/null -w '%{http_code}'` (no `-L`). The
`/platform/environments` URL above was the only one returning a 3xx;
every other URL already returned a direct 200.

## Verification
- Derived the old -> final path mapping directly from `warpdotdev/docs`'
`vercel.json` redirects (including the
`/agent-platform/cloud-agents/:path*` -> `/platform/:path*` rule and its
specific overrides) rather than assuming a prefix-only replace.
- Repo-wide search confirms zero remaining
`docs.warp.dev/agent-platform` occurrences in the touched files.
- Re-checked every rewritten docs URL touched by this PR against the
live site with a **no-follow** `curl -sS -o /dev/null -w '%{http_code}'`
(not `-L`): all 31 now resolve directly with HTTP 200, no redirect hop.
- `cargo fmt --check` and `cargo check -p warp --all-targets` pass.
- Testing-exempt: this is a pure string-literal/copy change (docs href
targets only) with no new logic or behavior — no regression test added,
per the testing-exempt "pure data/copy" category.
