a4d521cf96 fix: make all_goals admit goals on failure (#5934)
New behavior: when in recovery mode, if any tactic fails in `all_goals`
then the metacontext is restored and all goals are admitted.

Without this, it can leave partially-solved metavariables and incomplete
goal lists.

99070bf304 feat: update toolchain on lake update (#5684)
Lake will now update a package's `lean-toolchain` file on `lake update`
if it finds the package's direct dependencies use a newer compatible
toolchain. To skip this step, use the `--keep-toolchain` CLI option.

Closes #2582. Closes #2752. Closes #5615.

### Toolchain update details

To determine "newest compatible" toolchain, Lake parses the toolchain
listed in the packages' `lean-toolchain` files into four categories:
release , nightly, PR, and other. For newness, release toolchains are
compared by semantic version (e.g., `"v4.4.0" < "v4.8.0"` and
`"v4.6.0-rc1" < "v4.6.0"`) and nightlies are compared by date (e.g.,
`"nightly-2024-01-10" < "nightly-2014-10-01"`). All other toolchain
types and mixtures are incompatible. If there is not a single newest
toolchain, Lake will print a warning and continue updating without
changing the toolchain.

If Lake does find a new toolchain, Lake updates the workspace's
`lean-toolchain` file accordingly and restarts the update process on the
new Lake. If Elan is detected, it will spawn the new Lake process via
`elan run` with the same arguments Lake was initially run with. If Elan
is missing, it will prompt the user to restart Lake manually and exit
with a special error code (4).

### Other changes

To implement this new logic, various other refactors were needed. Here
are some key highlights:

* Logs emitted during package and workspace loading are now eagerly
printed.
* The Elan executable used by Lake is now configurable by the `ELAN`
environment variable.
* The `--lean` CLI option was removed. Use the `LEAN` environment
variable instead.
* `Package.deps` / `Package.opaqueDeps` have been removed. Use
`findPackage?` with a dependency's name instead.
* The dependency resolver now uses a pure breadth-first traversal to
resolve dependencies. It also resolves dependencies in reverse order,
which is done for consistency with targets. Latter targets shadow
earlier ones and latter dependencies take precedence over earlier ones.
**These changes mean the order of dependencies in a Lake manifest will
change after the first `lake update` on this version of Lake.**

93dd6f2b36 feat: add Int16/Int32/Int64 (#5885)
This adds all fixed width integers with the exception of `ssize_t` so
the code is quick to review as everything just behaves the same.

c61ced3f15 feat: introduce synthetic atoms in bv_decide (#5942)
This introduces a notion of synthetic atoms into `bv_decide`'s
reflection framework. An atom can be declared synthetic if its behavior
is fully specified by additional lemmas that are added in the process of
creating it. This is for example useful in the code that handles `if` as
the entire `if` block is abstracted as an atom and then two lemmas to
describe either branch are added. Previously this had the effect of
creating error messages about potentially unsound counterexamples, now
the synthetic atoms get filtered from the counter example generation.

### Compiler, runtime, and FFI
* [#4685](https://github.com/leanprover/lean4/pull/4685) fixes a typo in the C `run_new_frontend` signature
* [#4729](https://github.com/leanprover/lean4/pull/4729) has IR checker suggest using `noncomputable`
* [#5143](https://github.com/leanprover/lean4/pull/5143) adds a shared library for Lake
* [#5437](https://github.com/leanprover/lean4/pull/5437) removes (syntactically) duplicate imports (@euprunin)
* [#5462](https://github.com/leanprover/lean4/pull/5462) updates `src/lake/lakefile.toml` to the adjusted Lake build process
* [#5541](https://github.com/leanprover/lean4/pull/5541) removes new shared libs before build to better support Windows
* [#5558](https://github.com/leanprover/lean4/pull/5558) make `lean.h` compile with MSVC (@kant2002)
* [#5564](https://github.com/leanprover/lean4/pull/5564) removes non-conforming size-0 arrays (@eric-wieser)
### Lake
* Reservoir build cache. Lake will now attempt to fetch a pre-built copy of the package from Reservoir before building it. This is only enabled for packages in the leanprover or leanprover-community organizations on versions indexed by Reservoir. Users can force Lake to build packages from the source by passing --no-cache on the CLI or by setting the LAKE_NO_CACHE environment variable to true. [#5486](https://github.com/leanprover/lean4/pull/5486), [#5572](https://github.com/leanprover/lean4/pull/5572), [#5583](https://github.com/leanprover/lean4/pull/5583), [#5600](https://github.com/leanprover/lean4/pull/5600), [#5641](https://github.com/leanprover/lean4/pull/5641), [#5642](https://github.com/leanprover/lean4/pull/5642).
* [#5504](https://github.com/leanprover/lean4/pull/5504) lake new and lake init now produce TOML configurations by default.
* [#5878](https://github.com/leanprover/lean4/pull/5878) fixes a serious issue where Lake would delete path dependencies when attempting to cleanup a dependency required with an incorrect name.
* **Breaking changes**
* [#5641](https://github.com/leanprover/lean4/pull/5641) A Lake build of target within a package will no longer build a package's dependencies package-level extra target dependencies. At the technical level, a package's extraDep facet no longer transitively builds its dependencies extraDep facets (which include their extraDepTargets).
### Documentation fixes
* [#3918](https://github.com/leanprover/lean4/pull/3918) `@[builtin_doc]` attribute (@digama0)
* [#4305](https://github.com/leanprover/lean4/pull/4305) explains the borrow syntax (@eric-wieser)

All dependencies of a package are visited in order before recursing to the
dependencies' dependencies. For example, given the dependency graph:
```
R
|- A
|- B
|- X
|- Y
|- C
```
Lake follows the order `R`, `A`, `B`, `C`, `X`, `Y`.
The logic behind this design is that users would expect the dependencies
they write in a package configuration to be resolved accordingly and would be
surprised if they are overridden by nested dependencies referring to the same
package.
For example, were Lake to use a pure depth-first traversal, Lake would follow
the order `R`, `A`, `B`, `X`, `Y`, `C`. If `X` and `C` are both the package
`foo`, Lake would use the configuration of `foo` found in `B` rather than in
the root `R`, which would likely confuse the user.

will always be of the form a `./<relPath>` (i.e., be relative to its
workspace). Thus, when relativized to this workspace, it will have the

a manifest, it will instead be locked as `<relPkgDir>/<relPath>`.

Updates the workspace, materializing and reconfiguring dependencies.
Dependencies are updated to latest specific revision matching that in `require`
(e.g., if the `require` is `@master`, update to latest commit on master) or
removed if the `require` is removed.
If `tuUpdate` is empty, all direct dependencies of the workspace's root will be
updated and/or remove. Otherwise, only those specified will be updated.
If `updateToolchain := true`, the workspace's toolchain is also updated to the
latest toolchain compatible with the root and its direct dependencies.
If there are multiple incomparable toolchain versions across them,
a warning will be issued and no update performed.
If an update is performed, Lake will automatically restart the update on the new
toolchain (via `elan`). If `elan` is missing, it will instead request a manual
restart from the user and exit immediately with `restartCode`.
**Dependency Traversal Order**
All dependencies of a package are visited in reverse order before recursing
to the dependencies' dependencies. For example, given the dependency graph:
```
R
|- A
|- B
|- X
|- Y
|- C
```
Lake follows the order `R`, `C`, `A`, `B`, `Y`, `X`.
The reason for this is two-fold:
1. Like targets, later requires should shadow earlier definitions.
2. Requires written by a user should take priority over those inherited
from dependencies.
Were Lake to use a depth-first traversal, for example, Lake would follow
the order `R`, `A`, `B`, `X`, `Y`, `C`. If `X` and `C` are both the package
`foo`, Lake would use the configuration of `foo` found in `B` rather than in
the root `R`, which would likely confuse the user.
