A small patch release that keeps `communique generate --github-release`
from throwing away a whole CI run over a malformed final tool call, and
tidies up the docs-site announcement banner on mobile.

## Fixed

- **Salvage partial `submit_release_notes` submissions** — When the
model calls `submit_release_notes` with malformed arguments 3 times in a
row (e.g. `changelog` as an array instead of a string, or `release_body`
truncated by `max_tokens`), the agent no longer aborts the run. At the
retry limit it now attempts a lenient parse of the most recent
submission: non-string fields are coerced (arrays join with newlines,
objects are JSON-stringified), missing fields are derived from what's
present (`changelog` ⇄ `release_body`, `release_title` from the body's
first line), and only when every content field is empty does the run
fail. Real-world CI runs like
[endevco/aube#24903381187](https://github.com/endevco/aube/actions/runs/24903381187)
used to burn their entire research budget on this; they now recover
automatically. ([#120](#120))

- **Better error diagnostics on unsalvageable submissions** — A new
`Error::MalformedSubmission` variant uses miette's `Diagnostic` to embed
the received JSON via `#[source_code]` and aggregate per-field reasons
across all attempts, so the CLI prints something like `missing
'release_body'; 'changelog' must be a string (got array)` alongside the
offending payload instead of the old opaque `malformed 3 times`.

- **Docs announcement banner on mobile** — On viewports ≤640px the
banner was rendering cramped: `flex-wrap: nowrap` forced the message
onto two squeezed lines and the "Read more" link sat jammed against the
text. The banner now switches to `flex-direction: column` so the message
and link stack cleanly, with a slightly smaller font, tighter
line-height, `text-wrap: balance` for even line breaks, and the × close
button pinned flush to the top-right corner. Matches the same fix
rolling out across the mise, hk, aube, pitchfork, usage, and fnox docs
sites. ([#119](#119)) (@jdx)

> [!NOTE]
> **Low Risk**
> Low risk release-metadata update (version bumps and changelog/CLI docs
regen) with no functional code changes; main risk is minor
documentation/changelog formatting errors.
> 
> **Overview**
> Prepares the `v1.0.4` patch release by bumping the crate/CLI version
across `Cargo.toml`, `Cargo.lock`, `communique.usage.kdl`, and the
generated docs (`docs/cli/*`).
> 
> Updates `CHANGELOG.md` with a new `1.0.4` *Fixed* entry, but also
changes formatting around the `1.0.2`/`1.0.0` sections (some headings
are now concatenated onto the same line).
