1_led_matrix: Game of Life example using LED matrix and removal of 4_switch_controlled_motor_normal and accordingly rearrange the rest of the folders

[5iri]

• This PR replaces the basic LED blink example for 1_led_matrix with a Conway’s Game of Life demo running on the SRA Board LED matrix using ESP-IDF, and cleans up the remaining examples/CI to match the new layout.

Changes

• LED matrix example
  • Rewrites 1_led_matrix/README.md to describe the Game of Life example, including build/flash instructions using idf.py and a note about
    configuring CONFIG_LED_MATRIX_ROWS and CONFIG_LED_MATRIX_COLUMNS to match the board.
  • Implements a Game of Life simulation in 1_led_matrix/main/main.c:
    • Initializes with a fixed pattern for 5x6 matrices, with sensible fallbacks (center blinker or middle row) for other sizes.
    • Treats the grid as toroidal (wrap-around) when counting neighbors.
    • Uses led_matrix_set_data instead of led_matrix_set_data_raw for updating the display.
    • Adjusts the frame delay to ~150 ms for a smoother animation.
    • Keeps the existing boot-time “blink all LEDs” check before starting the Game of Life loop.
• Example layout & CI
  • Removes the deprecated 4_switch_controlled_motor_normal example and its references.
  • Renumbers the remaining examples to close the gap:
    • 5_PWM -> 4_PWM
    • 6_line_following -> 5_line_following
    • 7_self_balancing -> 6_self_balancing
  • Updates the Examples table in README.md to reflect the new directory names and paths.
  • Updates .github/workflows/test-build-app.yml so the build matrix tests the new example set: 1_led_matrix, 2_LSA, 3_MPU, 4_PWM, 5_line_following, 6_self_balancing.
  • Updates .gitmodules so the websocket submodule now lives at 6_self_balancing/components/websocket, matching the renumbered self-balancing example and fixing missing websocket_server.h during CI builds.

working proof.

[5iri]

ahhh ci pipeline needs to change to 1_led_matrix instead of 1_led_blink LOL

[vovw]

@5iri fix the ci/cd, looks like it still does cd 1_ledblink

[Shankari02]

The point of keeping led_blink simple is for fys to understand the code flow and as such how the build works, why to complicate it?

[Shankari02]

This should probably given as an assignment and the codebase should contain a basic file to blink all leds in a simple pattern

my thought process is that, the example in sra-board-component is already simple enough. Hence, why not make something nice to look at in the Wall-E Repo.

Wanted to up the standards of understanding as well. Wall-E is simple as is.

@5iri rebase and update, thanks

[5iri]

done @vovw ! check now!

[5iri]

#170 done.

[vovw]

@Shankari02 it works yay

[vovw]

lgtm

[Shankari02]

Please update the PR description to refer the multiple changes i.e. removal of switch controlled bot and renaming of files along with the ip fix, thanks!

[5iri]

ip fix is not part of this pr, but I'll update the rest in the description.

[Shankari02]

okay
