chore(uvicorn): Remove uv source of uvicorn PR

[schloerke]

With Kludex/uvicorn#2602, the expected behavior is achieved and this PR's changes in _main.py may be reverted.

---

We are close to a release and can not have a uv source in the pyproject.toml. Therefore, we're removing it and extending the reload-excludes to exclude any file within shiny_bookmarks up to 5 sub-folders deep. This should be a near 100% coverage.

Reprex express app

import pandas as pd

from shiny import reactive
from shiny.bookmark import BookmarkState
from shiny.express import app_opts, input, module, render, session, ui
from shiny.types import FileInfo

app_opts(bookmark_store="server")


@session.bookmark.on_bookmarked
async def _(url: str):
    await session.bookmark.update_query_string(url)


@module
def mymod(input, output, session):
    @reactive.effect
    @reactive.event(input.file1, ignore_init=True)
    async def _():
        # When the user interacts with the input, we will bookmark the state.
        await session.bookmark()

    @session.bookmark.on_bookmark
    async def _(state: BookmarkState):
        # After saving state, we will update the query string with the bookmark URL.
        print("Writing to file")
        (state.dir / "example.py").write_text("here!")

    ui.input_file("file1", "Choose File", multiple=True)

    @render.code
    def parsed_file():
        return str(input.file1())


mymod("test")

When uploading a file, it saves the bookmark state. Before the PR will cause a reload. With PR, layers are covered up to 5 module layers deep.
