New server/saip_profile.py encodes a DER ProfileElement sequence (ProfileHeader
with ICCID + Milenage AKA parameters carrying Ki/OPc) using asn1tools against
the official PE_Definitions SAIP ASN.1 schema. It locates the schema from an
installed osmocom pySim (or SAIP_ASN_PATH) via find_spec WITHOUT importing
pySim's Python package, so it avoids the pyscard/smpp card-reader stack — the
only runtime dep is asn1tools.
Selectable via profile.format ("v2" default | "saip"); the app falls back to
profile-package-v2 with a warning when SAIP prerequisites are absent. IMSI and
other EFs (USIM-template PEs) are the documented next layer.
Add requirements-saip.txt, pytest.ini (silence asn1tools warnings), README and
config updates. Tests: +6 (encode/round-trip/credentials, app emit + fallback);
92 pass.

Replace the placeholder README with a full operational guide: architecture,
user flow, quick start, config table, API reference (token profile URLs,
admin-token-gated export), profile-package-v2 format, Pi/Android deployment,
core sync, security notes, testing, and project layout.
