feat(flutter): update UI theme to monochrome with eagle watermark

Previous scheme conflated "which release is this" with "how many times has
it been rebuilt": every run bumped the patch version, so by the time a build
was ready to promote to master the version number had already crept forward
by however many alpha/beta iterations it took to get there.

Now a release cycle has one fixed target version (e.g. 0.4.1) that stays in
every manifest unchanged through all alpha/beta iterations; only a
per-channel counter increments, and that counter lives ONLY in the git tag,
never in Cargo.toml:

  v0.4.1-alpha.1 -> v0.4.1-alpha.2 -> ... -> v0.4.1-alpha.N
  v0.4.1-beta.1  -> v0.4.1-beta.2  -> ... -> v0.4.1-beta.N
  v0.4.1                                          <- master, iteration dropped

Deliberately "0.4.1-alpha.N" (dot AFTER the hyphen — a semver pre-release
identifier), not "0.4.1.N-alpha" (a 4th dot component before the hyphen):
the latter isn't valid semver and Cargo's version parser rejects it outright,
so it can never appear in Cargo.toml. That's also why the target version
itself never needs to change on a plain iteration — bumping every manifest +
refreshing both Cargo.locks is now skipped entirely unless -Switch actually
changes the target, making a routine alpha/beta push fast (just the state
file's counter + a tag).

Also fixes a real bug found while touching this: release.yml's push trigger
is tags-only ("v*") with no branch trigger, so the old `git push origin
$branch`-only path for alpha/pre-release never actually started a CI run —
only the master path (which already pushed a tag) worked. Every channel now
always pushes a real tag, which is what actually triggers the build.

release.yml's resolve-channel needed no changes: its tag-channel detection
already does substring matching (*-alpha*/*-beta*), so it classifies
"v0.4.1-alpha.37" correctly without modification.

-Prefix is gone — channel was always 1:1 with -Branch (alpha/pre-release/
master), so it was a redundant, independently-settable axis that could
silently drift from the branch (e.g. -Branch alpha -Prefix beta).

 .SYNOPSIS
-  Cuts a new OSTP release and pushes it to the channel that triggers the
-  matching GitHub Actions build (see .github/workflows/release.yml).
+  Cuts a new OSTP release and pushes the tag that triggers the matching
+  GitHub Actions build (see .github/workflows/release.yml, which only
+  triggers on "v*" tag pushes + workflow_dispatch — a bare branch push
+  does NOT start a build).
 
 .DESCRIPTION
-  Three release channels, in increasing order of stability:
-    alpha      -> pushes the `alpha` branch     -> tag "{version}-alpha"
-    pre-release  -> pushes the `pre-release` branch  -> tag "{version}-beta"
-    master       -> pushes an actual "v{version}" tag -> real stable release
+  A release cycle has ONE fixed target version (e.g. "0.4.1") that stays in
+  Cargo.toml/tauri.conf.json/package.json unchanged through every alpha and
+  beta build — only a per-channel ITERATION counter increments, and that
+  counter lives ONLY in the git tag, never in the manifests:
 
-  Promoting to pre-release/master first fast-forwards that branch to
-  `alpha` (--ff-only - this always succeeds cleanly as long as nobody ever
-  commits directly to pre-release/master, per CONTRIBUTING.md's branch
-  strategy), so a release always ships alpha's latest, not a stale branch.
+    v0.4.1-alpha.1  ->  v0.4.1-alpha.2  ->  ...  ->  v0.4.1-alpha.100
+    v0.4.1-beta.1   ->  v0.4.1-beta.2   ->  ...  ->  v0.4.1-beta.100
+    v0.4.1                                                <- master: iteration dropped
 
-  Remembers the last {version, branch, prefix} it used in .release-state.json
-  at the repo root. Running with no arguments repeats last time's branch and
-  prefix, auto-incrementing the patch version. -Switch starts a new version
-  line (e.g. 0.3.x -> 0.4.0) without changing branch/prefix. -Branch/-Prefix
-  override just that one setting for this run (and become the new default).
+  This is deliberately NOT "0.4.1.5-alpha" (a 4th dot-separated component
+  before the hyphen) — that is not valid semver, and Cargo's version parser
+  rejects it outright. "0.4.1-alpha.5" (dot AFTER the hyphen, a semver
+  pre-release identifier) is the only form that keeps Cargo.toml itself
+  parseable, so that's the only place the iteration number is allowed to
+  live: the git tag.
+
+  Promoting to beta/master first fast-forwards that branch to `alpha`
+  (--ff-only — this always succeeds cleanly as long as nobody ever commits
+  directly to pre-release/master, per CONTRIBUTING.md's branch strategy), so
+  a release always ships alpha's latest, not a stale branch. Switching to a
+  channel for the first time in a cycle resets THAT channel's iteration
+  counter to 1 (a fresh promotion starts its own count; it doesn't inherit
+  wherever alpha's counter happened to be).
+
+  Remembers {target_version, branch, alpha_iteration, beta_iteration} in
+  .release-state.json at the repo root. Running with no arguments repeats
+  last time's branch, bumping that channel's iteration by one — manifests
+  are NOT touched (nothing to bump: the target version hasn't changed).
+  -Switch starts a new target version line and resets both iteration
+  counters to 0 — THIS is the one case that bumps every manifest.
 
 .PARAMETER Switch
-  Set an exact version (e.g. "0.4.0") instead of auto-incrementing the patch
-  of the last released version. Becomes the new baseline for future bare runs.
+  Set a new target version (e.g. "0.4.2") instead of continuing the current
+  one. Resets both alpha_iteration and beta_iteration to 0. Defaults the
+  channel back to alpha unless -Branch is also given this run.
 
 .PARAMETER Branch
-  Which branch to release from: master, pre-release, or alpha.
+  Which branch/channel to release from: master, pre-release (beta), or alpha.
   Defaults to whatever was used last time (see .release-state.json).
 
-.PARAMETER Prefix
-  Tag suffix for non-stable channels: beta or alpha. Ignored (forced empty)
-  when -Branch master, since stable releases are bare "vX.Y.Z" tags.
-  Defaults to whatever was used last time.
-
 .EXAMPLE
   .\scripts\gha.ps1
-  Re-releases the same branch/prefix as last time, with the patch version bumped by 1.
+  Bumps the current channel's iteration by one and pushes v{target}-{channel}.{N}.
 
 .EXAMPLE
-  .\scripts\gha.ps1 -Switch 0.4.0
-  Starts releasing the 0.4.x line from now on; this run ships exactly 0.4.0.
+  .\scripts\gha.ps1 -Switch 0.4.2
+  Starts a fresh 0.4.2 cycle: manifests -> 0.4.2, alpha iteration resets to 1,
+  ships v0.4.2-alpha.1.
 
 .EXAMPLE
-  .\scripts\gha.ps1 -Branch pre-release -Prefix beta
-  Promotes alpha -> pre-release and ships "{version}-beta".
+  .\scripts\gha.ps1 -Branch pre-release
+  Promotes alpha -> pre-release (beta channel), resets beta_iteration to 1
+  (or bumps it if already mid-beta), ships v{target}-beta.{N}.
+
+.EXAMPLE
+  .\scripts\gha.ps1 -Branch master
+  Promotes to master and ships the bare v{target} stable tag — no iteration.
