release: prep v26.6.3 (version bump + CHANGELOG + doc refresh)

Release prep for v26.6.3

Bumps the version and refreshes documentation for the 58 commits since v26.6.2 (2026-06-07). No tag is created — tagging is the release trigger (the #3567 MS Store automation fires on v* tags), so that step is left to the maintainer after this merges.

Version

• CMakeLists.txt: VERSION 26.6.2 → 26.6.3 (drives the MSIX Identity.Version).
• README.md + AGENTS.md "current version" strings updated to match.

CHANGELOG.md — v26.6.3 entry

Covers: WFM software demodulator, APRS client, PSK Reporter reception map + reusable Qt mapping engine (QGeoView), Direwolf-derived VHF AFSK demodulator, DAX-IQ made fully usable, profile-load recovery hardening, DEXP protocol fix, Multi-Flex ping-watchdog grace, MQTT enhancements, the #3351 MainWindow decomposition + RadioSession, the MS Store CI auto-stage, and the fix roll-up.

Doc refresh (reviewed all repo-root + docs/ files)

• README.md — Highlights: added WFM, AetherModem packet/APRS, PSK Reporter map.
• ROADMAP.md — cycle → post-v26.6.3; moved AetherModem Phase 1 from Queued to Recently shipped alongside WFM / AFSK / PSK-Reporter map / DAX-IQ / the decomposition.
• AGENTS.md — version, added RadioSession to Key classes, threads 11 → 12.
• CONTRIBUTING.md — thread count 11 → 12.
• docs/architecture/pipelines.md — added the AX.25 TNC thread (feat(tnc): isolate AX.25 shim on dedicated QThread #3473) to the list + table; 11 → 12.
• docs/MODEM.md — VHF 1200 baud now documents the Direwolf-derived Profile A+ demodulator (9 slicers) that replaced the libmodem lane bank (feat(tnc): Direwolf-derived AFSK demodulator for VHF 1200-baud AX.25 #3527); the APRS client + map are no longer "out of scope" (HF 300-baud section unchanged).

Reviewed (via two parallel doc-review agents) and found no changes needed in: CONSTITUTION, GOVERNANCE, SUPPORT, SECURITY, CODE_OF_CONDUCT, CLAUDE/GEMINI (pointer files), and the rest of docs/ (audio-pipeline, vita49-format, tci-*, style/, theming/, qa/, etc.).

Verification

• Builds clean with VERSION 26.6.3; full suite 38/38 pass.

To roll the release (maintainer)

After merge: git tag -s v26.6.3 && git push origin v26.6.3 → triggers the Windows installer / release workflows (and the MS Store draft-stage once its credentials are set).

Thanks for the thorough release prep, @ten9876 — this is a clean, well-organized bump. I spot-checked the load-bearing doc claims against the tree and they hold up:

• Version sync is consistent across CMakeLists.txt, README.md, and AGENTS.md (26.6.3). Good catch that AGENTS.md was stale at 26.5.2.1 while README was already on 26.6.2 — resyncing it here is the right call.
• Thread count 11 → 12 is accurate: AetherAx25LibmodemShim is genuinely moved onto its own QThread (m_shim->moveToThread(&m_shimThread) in Ax25HfPacketDecodeDialog.cpp:809), and it's on-demand as the pipelines.md row says.
• MODEM.md AFSK rewrite matches the code: kVhf1200SpaceGains is std::array<float, 9> (9 slicers ✓), and the now-removed prose referenced kVhf1200FreeRunPhaseCount / kVhf1200PllAlphas, which no longer exist — so dropping them was correct, not just cosmetic.
• RadioSession exists (src/models/RadioSession.h), consistent with the AGENTS/CHANGELOG/ROADMAP additions.

One small fix before merge:

docs/MODEM.md points readers to a non-existent file:

the vendored demodulator and its parameters are documented in third_party/direwolf_afsk/ (AETHERSDR-PATCHES.md + the source headers).

The actual file in that directory is README.aethersdr.md (there's no AETHERSDR-PATCHES.md). Worth correcting the reference so the doc link resolves.

Scope is appropriate — all changes are version/CHANGELOG/doc-refresh as described, no code touched, and leaving the tag to the maintainer is the right move. With the filename reference fixed, this looks good to me.

(COMMENT only — leaving merge/tag to the maintainer.)
