Removes the last reason this repository depends on its own history.
The pin was deliberate and carried its own exit condition, written into the
comment above it: "revert to the path dependency the day the tag is an ancestor
of `main`." Measured -- `formats-pin-2026-09-01` (e2630413) IS an ancestor of
`main` now, so the condition is met, and the cost the comment named goes away
with it: while the pin held, `sylpheed-cli` built from the workspace crate and
the exporter from the tag, so `tools/port/verify-screen` compared two eras
instead of detecting drift. They read one decoder again.
It also removes a failure mode nobody priced in. Depending on this repo by tag
is what made the #49 history rewrite break the build: every commit was replaced,
the locked rev vanished, and clean checkouts could not resolve it while the
rewriting machine kept working off its `~/.cargo/git` cache (PR #60). A path
dependency cannot fail that way. `Cargo.lock` now has ZERO references to
Sylpheed.git.
⚠️ This moves the exporter across a 243-file decoder change (8 467 insertions),
so it was gated on the full suite rather than a compile:
45 suites / 377 passed / 0 failed / 14 ignored, cargo exit 0
45 binaries launched, 45 reported (a SIGKILLed suite prints no result line
and would otherwise vanish from the tally)
