1. M3 demo README provenance (tools/package/build_m3_demo.sh)

• Branch pr/3-tls-r1 has moved past f3df8261 (the image's commit); the README no longer presents the branch as the image's source. FIRMWARE_SOURCE now points at tree/f3df8261b59ea5883cc5b6d9bb1eb4c79f8f0fd4; the branch is named only as where development continues (head of draft PR TLS client sockets for the U64, through its ESP32 GideonZ/1541ultimate#997). Provenance phrasing follows the firmware side's 2026-10-15 suggestion. MEASURED_FW, FIRMWARE_PRERELEASE, FIRMWARE_IMAGE_SHA unchanged.
• UPSTREAM_PRS was stale. Checked with gh: GideonZ/1541ultimate #995 and #994 (issues) and #997, #996 (drafts) are open, none merged. The comment now says to change it when any of #994-#997 changes state. Cross-repo refs are qualified.

2. README make -n bullet
#174 is fixed. Verified here with 28 objects built: make -n BACKEND=uci HTTPS_SNI=example.org printed the "DRY RUN ... NOTHING was deleted" warning, then "Nothing to be done" on a fresh tree with make -q exiting 0. After touch src/http.s, make -n listed only the http.o recompile and the link, and make -q exited 1, so the bullet scopes the claim to what timestamps make stale; objects stayed 28 and the PRG survived. So the bullet now says the compare still runs and warns, the exemption is from writing/deleting only, and that the warning is the only signal because -n/-q describe the old tree. Also notes the MAKEFLAGS=/MFLAGS= parse-time error.

Overlap with #303: it edits README.md around lines 19, 39, 192; this PR ~452. None.
