Calculate graphite insert geometry that conforms to chamber internal contour.

The graphite insert:
1. Follows the chamber gas boundary (inner surface)
2. Has variable thickness based on local heat flux
3. Extends from graphite_start to graphite_end

Parameters:

    Gas boundary radius along chamber [m]
heat_flux_chamber : np.ndarray
    Heat flux along chamber [W/m²]
graphite_config : GraphiteInsertConfig
    Graphite configuration
graphite_start : float
    Graphite insert start position [m]
graphite_end : float
    Graphite insert end position [m]
recession_graphite : float
    Cumulative graphite recession [m]

Returns:
--------
geometry : dict
    - positions: Axial positions in graphite region [m]
    - R_inner: Inner radius (gas boundary) [m]
    - R_outer: Outer radius (graphite outer) [m]
    - thickness: Local thickness [m]
    - thickness_remaining: Remaining thickness [m]

		Optional[np.ndarray]	recession_profile = None )

Calculate variable thickness graphite insert profile conforming to chamber geometry.

The graphite insert follows the chamber internal contour (gas boundary) with
thickness varying based on local heat flux and thermal requirements.

Parameters:

positions : np.ndarray
    Axial positions [m]
R_gas : np.ndarray
    Gas boundary radius [m] (chamber internal contour)
heat_flux_profile : np.ndarray
    Local heat flux [W/m²] at each position
graphite_config : GraphiteInsertConfig
    Graphite configuration
recession_profile : np.ndarray, optional
    Local recession [m] at each position

Returns:
--------
profile : dict
    - R_inner: Inner radius (gas boundary) [m]
    - R_outer: Outer radius (graphite outer surface) [m]
    - thickness: Local thickness [m]
    - thickness_remaining: Remaining thickness after recession [m]
