This PR fixes some issues with our previous approach to synching LLM
usage over to Stripe.

We now have a separate LLM access price in Stripe that is a marker price
to allow us to create the initial subscription with that as its
subscription item

We then dynamically set the LLM usage price during the reconciliation
sync based on the usage for the current month.

Reworks the way tasks are stored, accessed and synchronized in the
`project`.
Now both collab and ssh remote projects use the same TaskStorage kind to
get the task context from the remote host, and worktree task templates
are synchronized along with other worktree settings.

Release Notes:

- Adds ssh support to tasks, improves collab-remote projects' tasks sync

This PR renames the `MONTHLY_SPENDING_LIMIT` constant to
`FREE_TIER_MONTHLY_SPENDING_LIMIT` to clarify it.

This will help distinguish it from the user's specified limit on their
paid monthly spending.

This PR adds a new `Cents` type that can be used to represent a monetary
value in cents.

This cuts down on the primitive obsession we were using when dealing

This snuck in last-minute.

Release Notes:

- Fixed a potential hang and panic when an SSH project goes through a
slow reconnect.

Instead of wrapping the search term with `\<...\>`, enable the
`WHOLE_WORD` search option.

The advantage of the search option is that it can be toggled with one
click/key press (alt+w by default), and it doesn't require regex mode.

Release Notes:

- Vim mode's whole word search now uses the search bar's "Match whole
words" option, instead of wrapping the search term with `\<...\>`. This
allows easier toggling of whole-word search, and it also works without
enabling the regex mode.

Closes #18722

- Replace the `@escape` capture name with `@string.escape` for escape
sequences in Go, Python, Regex, Racket, Ruby, and Scheme.
- Rust
  - Add syntax highlighting for escape sequences. Close #18722
- Fix the issue where `@punctuation.delimiter` is being overwritten by
`@operator`.
  - Add the period (".") to `@punctuation.delimiter`.

Release Notes:

We have a lot of data in Clickhouse. This column was used when migrating
the events dataset between analytics databases and has no purpose today.

Naive maths: 257,170,993 editor event rows * 1 byte per boolean =
257,170,993 bytes, or ~0.24 GB

I'll drop the column after deploying a new collab.

Going forward, I'd like to remove more data that we never touch, to try
to keep things more focused. We should discuss some TTL at some point.

This ensures that we only ever reconnect to a running server and not
spawn a new server with no state.

This avoids the problem of the server process crashing, `proxy`
reconnecting, starting a new server, and the user getting errors like
"unknown buffer id: ...".

After https://github.com/rust-lang/rust-analyzer/pull/18167 and certain
people who type and complete rapidly, it turned out that we have not
waited for `completionItem/resolve` to finish before applying the
completion results.

Release Notes:

- Fixed completion items applied improperly on fast typing

This fixes the problem of a `Project` sometimes not being dropped when
closing the single, last window of Zed.

Turns out, it wasn't get dropped for the following reason:

1. `editor::Editor` held a reference to project
2. The macOS `input_handler` on the `Window` held a reference to that
`Editor`
3. The AppKit window (and its input handler) get dropped asynchronously
(in the code in this diff), after the window is closed.
4. After the window is closed and no `cx.update()` calls are made
anymore, `flush_effects` is not called anymore.
5. But `flush_effects` is where we dropped entities that don't have any
more references.

In short: we dropped `Editor`, which held a reference to `Project`, out
of band, `flush_effects` wasn't called anymore, and thus the `Project`
wasn't dropped.

This PR updates the telemetry events sent to collab to use
`Content-Type: application/json` instead of `Content-Type: text/plain`.

The POST bodies are JSON, so `application/json` is the correct MIME
type.

I suspect the `text/plain` is a remnant from when the events were still
going through Vercel.

This PR makes the `github_user_login` field required in the
`LlmTokenClaims`.

We previously added this in
https://github.com/zed-industries/zed/pull/16316 and made it optional
for backwards-compatibility.

It's been more than long enough for all of the previous LLM tokens to
have expired, so we can now make the field required.

Release Notes:

This PR reworks our existing billing code in preparation for charging
based on LLM usage.

We aren't yet exercising the new billing-related code outside of
development.

There are some noteworthy changes for our existing LLM usage tracking:

- A new `monthly_usages` table has been added for tracking usage
per-user, per-model, per-month
- The per-month usage measures have been removed, in favor of the
`monthly_usages` table
- All of the per-month metrics in the Clickhouse rows have been changed
from a rolling 30-day window to a calendar month
