ogar-render-askama: render_python — Python import-shape emit PoC (SDK + package)

The Python counterpart of render_osm: same ruff → OGAR substrate, a
language-pluggable emit back-end. Proves the pull-back side of the transpiler
is not Rust-specific — OSM (and odoo) come out of the one substrate in Python
import shape, just like Rust.

Emits under python/:
- osm/models.py           — one @DataClass per THINK class; associations →
                            typed id fields; each grounded model has CLASS_ID.
- osm/controllers/<name>.py — the DO arm as a FAITHFUL mirror of app/controllers/,
                            one module per source controller by its verbatim
                            (snake) name — `osm.controllers.nodes.show(inp)`,
                            standalone, not methods. No singularisation (mirrors
                            the Rust `controllers` module).
- osm/__init__.py         — re-exports each controller at the package root
                            (`osm.nodes` ≡ `osm.controllers.nodes`) + CLASS_IDS.
- ogar_sdk.py             — the substrate-pull SDK (Python mirror of Rust
                            lance_graph_contract::ogar_codebook): CODEBOOK +
                            class_id(concept) + render_classid(concept, prefix)
                            (canon-high). Ships OSM (0x0F) AND odoo/commerce
                            (0x02) — the pull is domain-agnostic.

Verified: example builds clean; py_compile green on package + SDK; functional
smoke — osm.controllers.nodes.show + re-exported osm.nodes.show both callable,
class_id('osm_node')=0xf01, render_classid('account_move',0x0002)=0x2020002,
osm.nodes.show({}) raises NotImplementedError('port Api::NodesController#show').

Stacks on #153 (the faithful-controllers / no-singulariser change) so the
container module names are verbatim (nodes/searches/capabilities, not
searche/capabilitie). Typed params (dict Input → typed) remain the ruff brick.
