chore(release): stamp v0.6.9

[bucknova]

Release stamp for v0.6.9 — no functional change.

Moves seventeen entries out of [Unreleased] under ## [0.6.9] — 2026-09-02
and bumps pyproject.toml, the README status line, and the docs-site hero
badge from 0.6.8.

This is a safety and correctness release, not a feature one. The headline
entries, in the order a user would care:

• Connecting a rig no longer keys it. Both modem control lines were
  asserted on port open, so on a DTR/RTS-keyed interface pressing Connect
  Rig put the radio on the air for the entire session — a dead carrier with
  nothing in the UI to show it.
• Kenwood and Elecraft transmissions no longer abort a second in. Reading
  PTT sent TX;, which on those radios is the command that keys the
  transmitter.
• rigctld connects against daemons that echo the command name — the
  likely reason it never worked for at least one reported user, and the real
  cause behind a bug we previously mis-diagnosed.
• Remote TX can no longer key the rig with every safeguard disarmed, and
  no longer freezes the app while the dead-man's-switch unkeys a wedged rig.

Plus: Settings no longer wipes extra gallery folders, Wraase SC2-120 decodes
the way we transmit it, invalid audio gains are clamped instead of reaching
the radio, three thread-affinity defects in the RX/TX audio paths, and three
embedded-web-server hardening fixes.

Caveat worth stating

None of the radio fixes has been confirmed against real hardware. They're
verified against vendor protocol documentation (Hamlib source for the Kenwood
and rigctld work), packet captures contributed by @worldwidedx, pyserial's
own source for the line-state behaviour, and regression tests that were each
checked to fail without their fix. But no Kenwood, Elecraft, or DTR/RTS-keyed
interface has actually run this code.

One correction to the release notes below. I have been testing this for days on my own Elecraft K4 using a locally python install. I can now test it with the released version of the app. Tim
