* Pin burner-redis below the Windows-crashing 0.1.7 release
burner-redis 0.1.7 crashes the interpreter (native fault, no Python traceback)
running the memory:// task backend under pytest-xdist on Windows — reproduced on
GitHub Actions windows-latest via the 'Upgrade checks' workflow, confirmed
absent on macOS/Linux with the identical dependency versions.
pydocket only floors burner-redis at >=0.1.6, so capping pydocket's own version
is not enough: a resolver remains free to pick the newest burner-redis
satisfying that floor. fastmcp-tasks previously pinned pydocket>=0.20.0 with no
upper bound, so a fresh 'pip install fastmcp[tasks]' today can resolve straight
into the broken combination for a real Windows user on the default backend.
Pin burner-redis<0.1.7 directly, which in turn caps pydocket to <0.20.2 (the
last release that doesn't itself require burner-redis>=0.1.7). Verified the pin
holds under both locked and --upgrade (highest) resolution.
* Scope the burner-redis pin to Windows only
burner-redis 0.1.7 is confirmed fine on macOS/Linux (full suite green there with
the identical upgraded dependencies) - only Windows crashes. The previous
unconditional pin blocked every platform from newer pydocket/burner-redis
releases unnecessarily. Add sys_platform == 'win32' to the burner-redis
constraint so only Windows installs are capped.
Verified via uv pip compile --python-platform: macOS/Linux resolve to
burner-redis 0.1.7 / pydocket 0.23.0 (unblocked); Windows resolves to
burner-redis 0.1.6 / pydocket 0.20.1 (still capped).

* Restore task snapshot via a worker-level dependency
`get_access_token()` returned `None` inside background tasks whenever
`FASTMCP_DOCKET_URL` pointed at a `redis+cluster://` URL. The write side
was fine — it went through `docket.redis()`, which is cluster-aware —
but fastmcp kept a parallel sync Redis client just to read the snapshot
back, and `Redis.from_url()` rejects the cluster scheme.
Docket 0.19.1 ships worker-level dependencies that resolve per task in
the same asyncio.Task as user code, so ContextVars propagate cleanly.
That lets us load the snapshot once via `restore_task_snapshot` and
drop the sync Redis path entirely. Sync helpers like
`get_access_token()` and `get_http_request()` now just read a
ContextVar; Docket is the sole Redis consumer.
Closes#3897

* Revert TaskKey stub to a plain return
NotImplementedError would fire at module import if anything evaluated
the default; a no-op stub keeps the module usable without the
fastmcp[tasks] extra, which is what we want.

pydocket 0.19.0 fixes the fakeredis 2.35.0 FakeConnection rename
internally, so we no longer need to carry the fakeredis ceiling
ourselves. Removes the direct fakeredis[lua]<2.35.0 dependency from the
tasks extra entirely — it's just a transitive of pydocket now.

* Comprehensive MCP Apps docs, string CallTool resolution, bump prefab-ui >=0.13.0
Rewrites the apps documentation as a learning journey: overview → Prefab apps
→ FastMCPApp → patterns → dev tools → custom HTML. Adds a new FastMCPApp page
covering composable apps with @app.tool()/@app.ui(), CallTool, forms, actions,
and composition. Teaches Rx() and set_initial_state() as the primary state API.
Adds string-based CallTool resolution so CallTool("save_contact") resolves to
the tool's global key, matching callable ref behavior. Requires prefab-ui 0.13.0
which passes strings through the tool resolver.
* Detect ambiguous string CallTool resolution across apps
* Simplify string name registry to plain dict (last-write-wins)
