fix(build): stop discarding the bindings/javascript release profile

[gHashTag]

Closes #2295

The defect

Cargo prints this on every invocation in this workspace, on master today:

warning: profiles for the non root package will be ignored, specify profiles at the workspace root:
package:   <repo>/bindings/javascript/Cargo.toml
workspace: <repo>/Cargo.toml

bindings/javascript/Cargo.toml declares opt-level = "z" and lto = true.
The crate is in the root members array, so Cargo discards both and builds it
with the default release profile (opt-level = 3, lto = false).
release.yml publishes that crate to npm with
wasm-pack build --target bundler --release, run from inside the crate
directory — but wasm-pack resolves the enclosing workspace, so the published
.wasm has been built speed-optimized and un-LTO'd.

Correction to the premise I was handed

The task that produced this PR described bootstrap/Cargo.toml as the crate
declaring the orphaned profile. That is not true of master — it is true
of the branch feat/wave-547/host-heapsort. On master,
bootstrap/Cargo.toml has no [profile] section at all, and a scan of every
Cargo.toml in the tree finds exactly one member declaring one:
bindings/javascript. Cargo's own warning names the same single file. The bug
is real; the crate named in the brief was not.

Why the profile was not moved to the workspace root

Moving [profile.release] verbatim to the root would apply opt-level = "z"
to all five other members, including the t27c compiler that 8+ workflows
build with cargo build --release -p t27c. That silently size-optimizes the
compiler — a far bigger behavioral change than the bug.

Scoping it per-package at the root is not possible; Cargo rejects it:

error: failed to parse manifest at `<repo>/Cargo.toml`

Caused by:
  `lto` may not be specified in a `package` profile

lto, panic and rpath cannot appear in a package profile override.

The change

One line pair in the root Cargo.toml: bindings/javascript moves from
members to exclude, joining bindings/python and tools/converter which
were already excluded. The crate becomes its own workspace root, so Cargo
honours its existing [profile.release] verbatim and only for that crate.

No profile value is added, removed or tuned. The [profile.release] block
in bindings/javascript/Cargo.toml is not touched by this PR.

Acceptance test — the warning is gone

Same command, same worktree, pristine origin/master (98c44f6) vs. this
branch, stderr captured to a file and byte-counted:

$ cargo metadata --no-deps --offline --format-version 1 1>/dev/null 2>err
BEFORE exit=0 stderr_bytes=384
AFTER  exit=0 stderr_bytes=0

=== BEFORE stderr ===
warning: profiles for the non root package will be ignored, specify profiles at the workspace root:
package:   .../bindings/javascript/Cargo.toml
workspace: .../Cargo.toml
=== AFTER stderr ===
=== (end) ===

Cargo now reports the crate as its own workspace root, which is what makes the
profile apply:

$ cd bindings/javascript && cargo metadata --no-deps --offline --format-version 1 | grep -m1 workspace_root
"workspace_root":".../bindings/javascript"

Honesty limits (BINDING)

• Binary size and build time were not measured, before or after, for either
  t27c or the .wasm. Free disk was 390 MiB and this workspace's
  target/ reaches ~1.1 GiB, so no release build was attempted. I have not
  demonstrated that the published .wasm gets smaller — only that Cargo now
  honours the profile it previously discarded. Someone with disk should run
  wasm-pack build --target bundler --release in bindings/javascript before
  and after and record both .wasm sizes.
• Loose end from exclusion: an excluded crate no longer shares the root
  Cargo.lock, and this PR does not add one for bindings/javascript, so its
  dependencies resolve freshly at release time and it leaves workspace-wide
  cargo build/cargo test coverage from the root. Nothing in CI depended on
  either (release.yml cds into the crate; no workflow greps for a clean
  tree), but unpinned resolution for a published npm artifact is a real gap,
  recorded rather than silently accepted.
