feat(overlays): fifteen functions adapted from the NTSC decomp

[cnobis]

Fifteen exact matches adapted from the NTSC decomp's matched C, one commit each. Each passed try_func.py (EXACT) and overlay_file_check.py (0 problems). The full build has no size mismatch, every function sits at its retail address, and the one known byte mismatch is unchanged. The report is regenerated in the last commit: 4389 of 5109.

Function	Level	What it does
func_L00_002629E0	shared	does a segment cross a path
func_L00_0020D3A0	shared	finds the ledge spot the hero can reach
func_L01_00303810	Novalis	full-screen tiled noise draw callback
func_L01_002F0B48	Novalis	spark burst around a moby
func_L06_002EAF90	Blarg	moves a moby, pushes it out of walls, snaps it to its path
func_L06_0030D3E8	Blarg	growing and fading sprite draw callback
func_L06_002F3D40	Blarg	nearest box or mine within reach
func_L09_002F1198	Gaspar	spawns a class 0x1A1 effect around a point
func_L09_0030BB28	Gaspar	spawns a moby from its owner's spawn class
func_L11_00310058	Pokitaru	tilting platform the hero tips over
func_L13_002EBD00	Gemlik	the tractor beam of Qwark's ship (below)
func_L14_002D8500	Oltanis	two glow quads for the plasmabot (class 211)
func_L14_00306BE0	Oltanis	the Morph-o-Ray pickup (class 1354), which starts a cutscene
func_L14_002FD578	Oltanis	class 908 (jet), five objects flying fixed paths
func_L18_002FABE0	Veldin 2	three nested glow quads

Corrections: two rows above first used the NTSC decomp's names, which do not match the objects:

• func_L14_002FD578 is not a mine cart. It updates class 908 (jet in the editor's class list), placed five times high above Oltanis, each flying a fixed path. Its code also handles a hit (mask 0x800000): the object stops and restarts at its path's start after a timer, and the third such hit in level 14 plays a voice line once.
• func_L14_002D8500 draws two glow quads for the plasmabot (class 211), not for a racer.

func_L14_00306BE0 is the update of the Morph-o-Ray pickup (class 1354). The commit messages keep the old wording.

Adapting them took more than renaming symbols:

• Level data sits 0x80 to 0xD0 above its US address, varying by level.
• A load through $at or through its own destination register means MACRO_ADDR, and a $gp load means SDATA.
• Two Oltanis dialogue ids are 5 higher in PAL (0x53DB and 0x53E5 for the US 0x53D6 and 0x53E0).
• Where a file already declares a callee with other parameter types, the function calls it through a second name, or takes the file's types and converts them inside.
• Moby fields the NTSC decomp names appear under their unkXX names from include/moby.h.

func_L13_002EBD00 is the tractor beam that Qwark's ship fires at Ratchet's ship in the Gemlik boss fight: the cone of white rings from the cannon under the ship. Its caller is the update of class 388 (qwarks_starfighter_part), which aims at the hero and draws the beam only while the ship faces him within 60 degrees. The function draws one ring-textured quad per unit from attachment point 0x13 toward the target, the rings flow along the beam over 20 frames, and the last 10 units fade out. The rings all have the same size. The cone shape in game is perspective, since the beam points at the player.

The cleanup commit drops the near misses and functional C of these fifteen, with their functional.tsv rows, and regenerates nonmatching/README.md with nonmatching.py's index(). That also brings three stale rows on main up to date.

Left out on purpose:

• func_L12_00304038 matches too, but its C needs a two-dimensional variable-length array. hostgen takes only one-dimensional ones, and the port uses the functional C only while a function is still assembly here. Landing it now would turn the Hoven effect back into a stub in the port, so it waits for hostgen.
• func_L14_002E1570 is 33 bytes off, from scheduling around a float constant.
• func_L15_002C62A8 matches in the NTSC decomp only through volatile reads that order the code, which this project does not allow.
